The operator shall further be able to show proof to the director or to any federal mine inspector concerned, that a suitable method was used to insure accuracy in the methods used in transposing other workings to the map of such mine.
There shall be an archive of underground coal mine maps maintained at the office of the director. The archive shall:
(1) Be secured in a fireproof and burglarproof vault;
(2) Have an appropriate map identification system; and
(3) Have adequate map microfilming facilities.
Whenever an operator permanently closes or abandons an underground coal mine, or temporarily closes an underground coal mine for a period of more than ninety days, he or she shall promptly notify the office of miners' health, safety and training and the federal mine inspector of the district in which such mine is located of such closure. Within sixty days of the permanent closure or abandonment of an underground coal mine, or, when an underground coal mine is temporarily closed, upon the expiration of a period of ninety days from the date of closure, the operator shall file with the office of miners' health, safety and training and such federal mine inspector a copy of the mine map revised and supplemented to the date of the closure. Such copy of the mine map shall be certified by a certified or professional engineer or licensed surveyor as aforesaid and shall be available for public inspection.
Any person having a map or surveying data of any worked out or abandoned underground coal mine shall make such map or data available to the Office of Miners' Health, Safety and Training to copy or reproduce such material.
Any person who fails or refuses to discharge any duty imposed upon him or her by this section is guilty of a misdemeanor, and, upon conviction thereof, shall be fined not less than $500 nor more than $1,000.
(a) A mine operator shall submit a detailed ventilation plan and any addendums to the director for review and comment. The mine operator shall review the plan with the director and address concerns to the extent practicable. The operator shall deliver to the miners' representative employed by the operator at the mine, if any, a copy of the operator's proposed annual ventilation plan at least ten days prior to the date of submission. The miners' representative, if any, shall be afforded the opportunity to submit written comments to the operator prior to such submission; in addition the miners' representative, if any, may submit written comments to the director. The director shall submit any concern that is not addressed to the United States Department of Labor - Mine Safety and Health Administration (MSHA) through comments to the plan. The mine operator shall provide a copy of the plan to the director ten days prior to the submittal of the plan to MSHA.
(b) The operator shall give the director a copy of the MSHA-approved plan and any addendums as soon as the operator receives the approval.
(c) In the event of an unforeseen situation requiring immediate action on a plan revision, the operator shall submit the proposed revision to the director and the miners' representative, if any, employed by the operator at the mine when the proposed revision is submitted to MSHA. The director shall work with the operator to review and comment on the proposed plan revision to MSHA as quickly as possible.
(d) Upon approval by MSHA, the plan is enforceable by the director. The approved plan and all revisions and addendums thereto shall be posted on the mine bulletin board and made available for inspection by the miners at that mine for the period of time that they are in effect.
(a) The ventilation of mines, the systems for which extend for more than two hundred feet underground and which are opened after the effective date of this article, shall be produced by a mechanically operated fan or mechanically operated fans. Ventilation by means of a furnace is prohibited in any mine. The fan or fans shall be kept in continuous operation, unless written permission to do otherwise be granted by the director. In case of interruption to a ventilating fan or its machinery whereby the ventilation of the mine is interrupted, immediate action shall be taken by the mine operator or the operator's management personnel, in all mines, to cut off the power and withdraw the men from the face regions or other areas of the mine affected. If ventilation is restored in fifteen minutes, the face regions and other places in the affected areas where gas (methane) is likely to accumulate, shall be reexamined by a certified person; and if found free of explosive gas, power may be restored and work resumed. If ventilation is not restored in fifteen minutes, all underground employees shall be removed from the mine, all power shall be cut off in a timely manner, and the underground employees shall not return until ventilation is restored and the mine examined by certified persons, mine examiners or other persons holding a certificate to make preshift examination. If ventilation is restored to the mine before miners reach the surface, the miners may return to underground working areas only after an examination of the areas is made by a certified person and the areas are determined to be safe.
(b) All main fans installed after the effective date of this article shall be located on the surface in fireproof housings offset not less than fifteen feet from the nearest side of the mine opening, equipped with fireproof air ducts, provided with explosion doors or a weak wall, and operated from an independent power circuit. In lieu of the requirements for the location of fans and pressure-relief facilities, a fan may be directly in front of, or over a mine opening: Provided, That such opening is not in direct line with possible forces coming out of the mine if an explosion occurs: Provided, however, That there is another opening having a weak wall stopping or explosion doors that would be in direct line with forces coming out of the mine. All main fans shall be provided with pressure-recording gauges or water gauges. A daily inspection shall be made of all main fans and machinery connected therewith by a certified electrician and a record kept of the same in a book prescribed for this purpose or by adequate facilities provided to permanently record the performance of the main fans and to give warning of an interruption to a fan.
(c) Auxiliary fans and tubing shall be permitted to be used in lieu of or in conjunction with line brattice to provide adequate ventilation to the working faces: Provided, That auxiliary fans be so located and operated to avoid recirculation of air at any time. Auxiliary fans shall be approved and maintained as permissible.
(d) If the auxiliary fan is stopped or fails, the electrical equipment in the place shall be stopped and the power disconnected at the power source until ventilation in the working place is restored. During such stoppage, the ventilation shall be by means of the primary air current conducted into the place in a manner to prevent accumulation of methane.
(e) In places where auxiliary fans and tubing are used, the ventilation between shifts, weekends and idle shifts shall be provided to face areas with line brattice or the equivalent to prevent accumulation of methane.
(f) The director may require that when continuous mine equipment is being used, all face ventilating systems using auxiliary fans and tubing shall be provided with machine-mounted diffuser fans, and such fans shall be continuously operated during mining operations.
(g) In the event of a fire or explosion in any coal mine, the ventilating fan or fans shall not intentionally be started, stopped, speed increased or decreased or the direction of the air current changed without the approval of the general mine foreman, and, if he or she is not immediately available, a representative of the Office of Miners' Health, Safety and Training. A duly authorized representative of the employees should be consulted if practical under the circumstances.
(a) The operator or mine foreman of every coal mine, whether worked by shaft, slope, or drift, shall provide and hereafter maintain for every such mine adequate ventilation. In all mines the quantity of air passing through the last open crosscut between the intake and return in any pair or set of entries shall be not less than nine thousand cubic feet of air per minute and as much more as is necessary to dilute and render harmless and carry away flammable and harmful gases. All working faces in a working section between the intake and return airway entries shall be ventilated with a minimum quantity of three thousand cubic feet of air per minute and as much more as is necessary to dilute and render harmless and carry away flammable and harmful gases. The quantity of air reaching the last crosscut in pillar sections may be less than nine thousand cubic feet of air per minute if at least nine thousand cubic feet of air per minute is being delivered to the intake of the pillar line. The air current shall under any conditions have a sufficient volume and velocity to reduce and carry away smoke from blasting and any flammable or harmful gases. The operator shall provide to the safety committee access to anonometers and smoke tubes while performing their duties. All active underground working places in a mine shall be ventilated by a current of air containing not less than nineteen and five-tenths percent of oxygen, not more than five-tenths percent of carbon dioxide, and no harmful quantities of other noxious or poisonous gases.
(b) Airflow shall be maintained in all intake and return air courses of a mine and, where multiple fans are used, neutral areas created by pressure equalization between main fans shall not be permitted. Production activities in working faces shall cease while tubing, line brattice or other ventilation devices are being installed inby the machine operator.
(c) Properly installed and adequately maintained line brattice or other approved devices shall be continuously used from the last open crosscut of an entry or room of each working section to provide adequate ventilation to the working faces for the miners and to remove flammable, explosive and noxious gases, dust, and explosive fumes. When damaged by falls or otherwise, such line brattice or other devices shall be repaired immediately.
(d) Brattice cloth used underground shall be of flame-resistant material. The space between the line brattice or other approved device and the rib shall be large enough to permit the flow of a sufficient volume and velocity of air to keep the working face clear of flammable, explosive and noxious gases, dust and explosive fumes.
(e) Each working unit newly developed in virgin coal hereafter, shall be ventilated by a separate split of air: Provided, That in areas already under development and in areas where physical conditions prevent compliance with this provision, the director may grant temporary relief from compliance until such time as physical conditions make compliance possible. The quantity of air reaching the last crosscut shall not be less than nine thousand cubic feet of air per minute and shall under any condition have sufficient volume and velocity to reduce and carry away smoke and flammable or harmful gases from each working face in the section.
(f) As working places advance, crosscuts for air shall be made not more than one-hundred-five feet apart. Where necessary to render harmless and carry away noxious or flammable gases, line brattice or other approved methods of ventilation shall be used so as to properly ventilate the face. All crosscuts between the main intake and return airways not required for passage of air and equipment shall be closed with stoppings substantially built with incombustible or fire-resistant material so as to keep working places well ventilated. In mines where it becomes necessary to provide larger pillars for adequate roof support, working places shall not be driven more than two hundred feet without providing a connection that will allow the free flow of air currents. In such cases, a minimum of twelve thousand cubic feet of air a minute shall be delivered to the last open crosscut and as much more as is necessary to dilute and render harmless and carry away flammable and noxious gases.
(g) In special instances for the construction of sidetracks, haulageways, airways or openings in shaft bottom or slope bottom layouts where the size and strength of pillars is important, the director may issue a permit approving greater distances. The permit shall specify the conditions under which such places may be driven.
(h) In all mines a system of bleeder openings on air courses designed to provide positive movement of air through and/or around abandoned or caved areas, sufficient to prevent dangerous accumulation of gas in such areas and to minimize the effect of variations in atmospheric pressure shall be made a part of pillar recovery plans projected after July 1, 1971.
(i) If a bleeder return is closed as a result of roof falls or water during pillar recovery operations, pillar operations may continue without reopening the bleeder return if at least twenty thousand cubic feet of air per minute is delivered to the intake of the pillar line.
(j) No operator or mine foreman shall permit any person to work where he is unable to maintain the quantity and quality of the air current as heretofore required: Provided, That such provisions shall not prohibit the employment of men to make place of employment safe.
(k) The ventilation of any mine shall be so arranged by means of air locks, overcasts or undercasts, that the use of doors on passageways where men or equipment travel may be kept to a minimum. Where doors are used in a mine, they shall be erected in pairs so as to provide a ventilated air lock unless the doors are operated mechanically.
(l) A crosscut shall be provided at or near the face of each entry or room before such places are abandoned.
(m) Overcasts or undercasts shall be constructed of incombustible material and maintained in good condition.
(n) After January 1, 1987, all run through check curtains shall be substantially constructed of translucent material, except that where belting material has to be used because of high velocity, there shall be a window of translucent material at least thirty inches square or one half the height of the coal seam, whichever is less.
(a) Definitions. -– For purposes of this section, "belt air" means the use of a belt conveyor entry as an intake air course to ventilate the working sections of a mine or areas where mechanized mining equipment is being installed or removed.
(b) Upon the effective date of the enactment of this section, belt air may not be used to ventilate the working sections of a mine or areas where mechanized mining equipment is being installed or removed: Provided, That if an alternative method of ventilation will at all times guarantee no less than the same measure of protection afforded the miners of an underground mine by the foregoing or if the application of the foregoing to an underground mine will result in a diminution of safety to the miners in the mine, the director may approve the interim use of belt air pursuant to the following:
(1) For those operators using belt air pursuant to a ventilation plan approved by the director in accordance with the provisions of section two of this article prior to the effective date of the enactment of this section, the director shall cause an inspection to be made of the mine ventilation system and ventilation equipment. The director may allow the continued use of belt air in that mine if he or she determines that: (i) The use meets the minimum requirements of 30 CFR 75.350(b); and (ii) the use, as set forth in the ventilation plan and as inspected, will at all times guarantee no less than the same measure of protection afforded the miners of the mine if belt air were not used, or that the prohibition of the use of belt air in the mine will result in a diminution of safety to the miners in the mine.
(2) For those operators submitting on or after the effective date of the enactment of this section, a ventilation plan proposing the use of belt air to the director pursuant to section two of this article, the director shall immediately upon receipt of the plan give notice of the plan to the representative of the miners in that mine and cause any investigation to be made that the director considers appropriate: Provided, That the investigation shall include a review of any comments on the plan submitted by the representative of miners in the mine. Upon receiving the report of the investigation, the director shall make findings of fact and issue a written decision, incorporating in the decision his or her findings and an order approving or denying the use of belt air pursuant to the terms of the ventilation plan. To approve the use of belt air pursuant to a ventilation plan, the director shall, at a minimum, determine that: (i) The operator's proposed use of belt air meets the minimum requirements of 30 CFR 75.350(b); and (ii) approval of the proposed use of belt air will at all times guarantee no less than the same measure of protection afforded the miners of the mine if belt air were not used, or that the prohibition of the use of belt air in the mine will result in a diminution of safety to the miners in the mine.
(3) The interim use of belt air shall be accurately reflected in operator's plan of ventilation, as approved by the director in accordance with the provisions of section two of this article.
(c) Upon completion of the independent scientific and engineering review concerning the use of belt air and the composition and fire retardant properties of belt materials in underground coal mining by the technical study panel created pursuant to the provisions of 30 U. S. C. §963 and the Secretary of the United States Department of Labor's corresponding report to Congress pursuant to the review, the Board of Coal Mine Health and Safety shall, within thirty days of the Secretary of Labor's report to Congress, provide the Governor with its recommendations, if any, for the enactment, repeal or amendment of any statute or rule which would enhance the safe ventilation of underground mines and the health and safety of miners: Provided, That at least sixty days after the Secretary of Labor's report to Congress, the Board of Coal Mine Health, Safety and Training shall promulgate emergency rules regulating the use of belt air in light of that report: Provided, however, That the provisions of subsections (a) and (b) of this section shall expire and no longer have any force and effect upon the filing of such emergency rules.
(a) In any mine, all workings which are abandoned after July 1, 1971, shall be sealed or ventilated. If the workings are sealed, the sealing shall be done with incombustible material in a manner prescribed by the director and one or more of the seals of every sealed area shall be fitted with a pipe and cap or valve to permit the sampling of gases and measuring of hydrostatic pressure behind the seals. For the purpose of this section, working within a panel shall not be considered to be abandoned until the panel is abandoned.
(b) Air that has passed through an abandoned area or an area which is inaccessible or unsafe for inspection shall not be used to ventilate any working place in any working mine, unless permission is granted by the director with unanimous agreement of the technical and mine safety review committee. Air that has been used to ventilate seals shall not be used to ventilate any working place in any working mine. Air which has been used to ventilate an area from which the pillars have been removed shall not be used to ventilate any working place in a mine, except that the air, if it does not contain 0.25 volume percent or more of methane, may be used to ventilate enough advancing working places immediately adjacent to the line of retreat to maintain an orderly sequence of pillar recovery on a set of entries. Before sealed areas, temporary or permanent, are reopened, the director shall be notified.
(c) On or after the effective date of the amendment and reenactment of this section during the 2007 regular session of the Legislature, a professional engineer registered with the Board of Registration for Professional Engineers pursuant to article thirteen, chapter thirty of this code shall certify the design of all new seals as meeting the criteria established by the director. Every seal design shall have the professional engineer's certificate and signature, in addition to his or her seal, in the following form:
"I the undersigned, do hereby certify that this seal design is, to the best of my knowledge, in accordance with all applicable requirements under state and federal law, rules and regulations.
(d) On or after the effective date of the amendment and reenactment of this section during the 2007 regular session of the Legislature, the director shall approve the construction of all new seals in accordance with rules authorized in this section. The construction shall also be:
(1) Certified by the mine foreman-fire boss of the mine as being in accordance with the design certified by a professional engineer pursuant to subsection (c) of this section; and
(2) (A) Constructed of solid concrete blocks and in accordance with the other provisions of 30 CFR 75.335(a)(1); or
(B) Constructed in a manner that the director has approved as having the capability to withstand pressure equal to or greater than a seal constructed in accordance with the provisions of 30 CFR 75.335(a)(1).
(e) On or after the effective date of the amendment and reenactment of this section during the 2007 regular session of the Legislature, the operator shall inspect the physical condition of all seals and measure the atmosphere behind all seals in accordance with protocols developed by the Board of Coal Mine Health and Safety, pursuant to rules authorized in this section and consistent with a mine-specific atmospheric measurement plan submitted to and approved by the director. The atmospheric measurements shall include, but not be limited to, the methane and oxygen concentrations and the barometric pressure. The atmospheric measurements also shall be recorded with ink or indelible pencil in a book kept for that purpose on the surface at a location designated by the operator. The protocols shall specify appropriate methods for inspecting the physical condition of seals, measuring the mine atmosphere in sealed workings, and inerting the mine atmosphere behind the seals, where appropriate.
(f) (1) In all mines containing workings sealed using seals constructed in accordance with the provisions of 30 CFR 75.335(a)(2) which are constructed: (A) Of cementitious foam blocks; or (B) with methods or materials that the Board of Coal Mine Health and Safety determines do not provide an adequate level of protection to miners, the operator shall, pursuant to a plan submitted to and approved by the director, remediate the seals by either enhancing the seals or constructing new seals in place of or immediately outby the seals. After being remediated, all seals must have the capability to withstand pressure equal to or greater than a seal constructed in accordance with the provisions of 30 CFR 75.335(a)(1). The design, development, submission and implementation of the remediation plan is the responsibility of the operator of each mine. Pursuant to rules authorized in this section, the Board of Coal Mine Health and Safety shall specify appropriate methods of enhancing the seals.
(2) Notwithstanding any provision of this code to the contrary, if the director determines that any seal described in subdivision (1) of this subsection is incapable of being remediated in a safe and effective manner, the mine foreman-fire boss shall, at least once every twenty-four hours, inspect the physical condition of the seal and measure the atmosphere behind the seal. The daily inspections and measurements shall otherwise be performed in accordance with the protocols and atmospheric measurement plan established pursuant to subsection (e) of this section.
(g) Upon the effective date of the amendment and reenactment of this section during the 2007 regular session of the Legislature, second mining of lower coal on retreat, also known as bottom mining, shall not be permitted in workings that will be sealed unless an operator has first submitted and received approval by the director of a remediation plan that sets forth measures that will be taken to mitigate the effects of remnant ramps and other conditions created by bottom mining on retreat which can increase the force of explosions originating in and emanating out of workings that have been bottom mined. The director shall require that certification in a manner similar to that set forth in subsection (c) of this section shall be obtained by the operator from a professional engineer and the mine foreman-fire boss for the plan design and plan implementation, respectively.

(c) The duties of the mine foreman and assistant mine foreman shall include the instruction of apprentice miners in the hazards incident to any new work assignments; to assure that any individual given a work assignment in the working face without prior experience on the face is instructed in the hazards incident thereto and supervised by a miner with experience in the tasks to be performed.
The mine foreman shall require that all slopes, incline planes and haulage roads used by any person in the mine shall conform to the provisions of this article.
On all haulways, where hauling is done by machinery of any kind, the mine foreman shall provide for a proper system of signals, and a conspicuous light or approved trip reflector on the rear of every trip or train of cars when in motion in a mine. When hoisting or lowering of miners occurs in the morning before daylight, or in the evening after darkness, at any mine operated by shaft, the mine foreman shall provide and maintain at the shaft mouth a light of stationary character, sufficient to show the landing and all surrounding objects distinctly, and sufficient light of a stationary character shall be located at the bottom of the shaft so that persons coming to the bottom may clearly discern the cages and other objects contiguous thereto. The mine foreman shall require that no cages on which miners are riding shall be lifted or lowered at a rate of speed greater than one thousand feet per minute and that no mine cars, either empty or loaded, shall be hoisted while miners are being lowered, and no cage having an unstable self-dump platform shall be used for the carrying of miners unless the same is provided with some device by which it may be securely locked when miners are being hoisted or lowered into the mine: Provided, however, That during the initial development of a mine, and only until the shafts are joined, miners shall be permitted to ride cages with one empty car which has been bolted or strapped to the cage.
It shall further be the duty of the mine foreman to have boreholes kept not less than twenty feet in advance of the face, one each twenty feet on sides of the working places that are being driven toward and in dangerous proximity to an abandoned mine or part of a mine which may contain inflammable gases or which is filled with water. These holes shall be drilled whenever any working place in an underground mine approaches within fifty feet of abandoned workings in such mine, as shown by surveys made and certified by a competent engineer or surveyor, or within two hundred feet of any abandoned workings of such mine which cannot be inspected.
§22A-2-12. Instruction of employees and supervision of apprentices; annual examination of persons using approved methane detecting devices; records of examination; maintenance of methane detectors, etc.
(a) The Office of Miners' Health, Safety and Training shall prescribe and establish a course of instruction in mine safety and particularly in dangers incident to employment in mines and in mining laws and rules, which course of instruction shall be successfully completed within twelve weeks after any person is first employed as a miner. It is further the duty and responsibility of the Office of Miners' Health, Safety and Training to see that the course is given to all persons as above provided after their first being employed in any mine in this state. In addition to other enforcement actions available to the director, upon a finding by the director of the existence of a pattern of conduct creating a hazardous condition at a mine, the director shall notify the Board of Miners' Training, Education and Certification, which shall cause additional training to occur at the mine addressing such safety issue or issues identified by the director, pursuant to article seven of this chapter.
(b) It is the duty of the mine foreman or the assistant mine foreman of every coal mine in this state to see that every person employed to work in the mine is, before beginning work therein, instructed in the particular danger incident to his or her work in the mine, and furnished a copy of the mining laws and rules of the mine. It is the duty of every mine operator who employs apprentices, as that term is used in sections three and four, article eight of this chapter to ensure that the apprentices are effectively supervised with regard to safety practices and to instruct apprentices in safe mining practices. Every apprentice shall work under the direction of the mine foreman or his or her assistant mine foreman and they are responsible for his or her safety. The mine foreman or assistant mine foreman may delegate the supervision of an apprentice to an experienced miner, but the foreman and his or her assistant mine foreman remain responsible for the apprentice. During the first one hundred twenty days of employment in a mine, the apprentice shall work within sight and sound of the mine foreman, assistant mine foreman, or an experienced miner, and in a location that the mine foreman, assistant mine foreman or experienced miner can effectively respond to cries for help of the apprentice. The location shall be on the same side of any belt, conveyor or mining equipment.
(c) Persons whose duties require them to use a approved methane detecting deviceor other approved methane detectors shall be examined at least annually as to their competence by a qualified official from the Office of Miners' Health, Safety and Training and a record of the examination shall be kept by the operator and the office. Approved methane detecting devices and other approved methane detectors shall be given proper maintenance and shall be tested before each working shift. Each operator shall provide for the proper maintenance and care of the permissible approved methane detecting device or any other approved device for detecting methane and oxygen deficiency by a person trained in the maintenance, and, before each shift, care shall be taken to ensure that the approved methane detecting device or other device is in a permissible condition and maintained according to manufacturer's specifications.
Before the beginning of any shift upon which they shall perform supervisory duties, the mine foreman or his assistant shall review carefully and countersign all books and records reflecting the conditions and the areas under their supervision, exclusive of equipment logs, which the operator is required to keep under this chapter. The mine foreman, assistant mine foreman or fire boss shall visit and carefully examine each working place in which miners will be working at the beginning of each shift before any face equipment is energized and shall examine each working place in the mine at least once every two hours each shift while such miners are at work in such places, and shall direct that each working place shall be secured by props, timbers, roof bolts, or other approved methods of roof support or both where necessary to the end that the working places shall be made safe. The mine foreman or his assistants upon observing a violation or potential violation of article two of this chapter or any regulation or any plan or agreement promulgated or entered into thereunder shall arrange for the prompt correction thereof. The foreman shall not permit any miner other than a certified foreman, fire boss, assistant mine foreman, assistant mine foreman-fire boss or pumper to be on a working section by himself Should the mine foreman or his assistants find a place to be in a dangerous condition, they shall not leave the place until it is made safe, or shall remove the persons working therein until the place is made safe by some competent person designated for that purpose.
He shall place his initials, time and the date at or near each place he examines. He shall also record any dangerous conditions and practices found during his examination in a book provided for that purpose.
It shall be the duty of the mine foreman, assistant mine foreman or fire boss to examine all working places under his or her supervision for hazards at least once every two hours during each coal-producing shift, or more often if necessary for safety. In all mines such examinations shall include tests with an approved detector for methane and oxygen deficiency. It shall also be his or her duty to remove as soon as possible after its discovery any accumulations of explosive or noxious gases in active workings, and where practicable, any accumulations of explosive or noxious gases in the worked out and abandoned portions of the mine. It shall be the duty of the mine foreman, assistant mine foreman or fire boss to examine each mine within three hours prior to the beginning of a shift and before any miner in such shift enters the active workings of the mine.
The mine foreman shall direct and see that all dangerous places and the entrance or entrances to worked out and abandoned places in all mines are properly dangered off across the openings.
The mine foreman shall, each day, read carefully and countersign with ink or indelible pencil all reports entered in the record book of the fire bosses. The mine foreman shall supervise the fire boss or fire bosses, except as provided in section twenty-one of this article. No less frequently than bi-weekly, the superintendent or, if there is no superintendent, the senior person at the mine shall obtain complete copies of the books of the fire bosses, and acknowledge that he or she has reviewed such copies and acted accordingly. This acknowledgment shall be made by signing a book prescribed by the director for that purpose.
The mine foreman shall give prompt attention to the removal of all dangers reported to him by his assistants, the fire boss or any other person working in the mine, and in case it is impracticable to remove the danger at once, he shall notify all persons whose safety is menaced thereby to remain away from the area where the dangerous condition exists. He or his assistants or certified persons designated by him shall at least once each week travel and examine the air courses, roads and openings that give access to old workings or falls and make a record of the condition of all places where danger has been found, with ink or indelible pencil in a book provided for that purpose.
§22A-2-18. Duty of mine foreman to notify operator when unable to comply with law; duty of operator.
The mine foreman shall notify, in writing, the operator or superintendent of the mine, and the director, of his inability to comply with any of the requirements of this law, and it shall then become the duty of such operator or superintendent promptly to attend to the matter complained of by the mine foreman so as to enable him to comply with the provisions hereof. Every operator of a mine shall furnish all supplies necessary for the mine foreman to comply with the requirements of this law after being requested to do so in writing by the mine foreman.
In case of the death or resignation of a mine foreman, the superintendent or manager shall appoint a certified man to act as mine foreman.
§22A-2-20. Preparation of danger signal by fire boss or certified person acting as such prior to examination; report; records open for inspection.
(a) It is the duty of the fire boss, or a certified person acting as such, to prepare a danger signal (a separate signal for each shift) with red color at the mine entrance at the beginning of his or her shift or prior to his or her entering the mine to make his or her examination and, except for those persons already on assigned duty, no person except the mine owner, operator or agent, and only then in the case of necessity, shall pass beyond this danger signal until the mine has been examined by the fire boss or other certified person and the mine or certain parts thereof reported by him or her to be safe. When reported by him or her to be safe, the danger sign or color thereof shall be changed to indicate that the mine is safe in order that employees going on shift may begin work. Each person designated to make the fire boss examinations shall be assigned a definite underground area of the mine, and, in making his or her examination shall examine all active working places in the assigned area and make tests with an approved device for accumulations of methane and oxygen deficiency; examine seals and doors; examine and test the roof, face and ribs in the working places and on active roadways and travelways, approaches to abandoned workings, accessible falls in active sections and areas where any person is scheduled to work or travel underground. He or she shall place his or her initials and the date at or near the face of each place he or she examines. Should he or she find a condition which he or she considers dangerous to persons entering the areas, he or she shall place a conspicuous danger sign at all entrances to the place or places. Only persons authorized by the mine management may enter the places while the sign is posted and only for the purpose of eliminating the dangerous condition. Upon completing his or her examination he or she shall report by suitable communication system or in person the results of this examination to a certified person trained as a certified miner with at least two years mining experience designated by mine management to receive and record the report, at a designated station on the surface of the premises of the mine or underground, before other persons enter the mine to work in coal-producing shifts. He or she shall also record the results of his or her examination with ink or indelible pencil in a book prescribed by the director, kept for the purpose at a place on the surface of the mine designated by mine management. All records of daily and weekly reports, as prescribed herein, shall be open for inspection by interested persons.
(b) Supplemental examination. - When it becomes necessary to have workers enter areas of the mine not covered during the preshift examination, a supplemental examination shall be performed by a fire boss or certified person acting as such within three hours before any person enters the area. The fire boss or certified person acting as such shall examine the area for hazardous conditions, determine if air is traveling in its proper direction and test for oxygen deficiency and methane.
(c) Each examined area shall be certified by date, time and the initials of the examiner.
(d) The results of the examination shall be recorded with ink or indelible pencil by the examiner in the book referenced in subsection (a) of this section before he or she leaves the mine on that shift.
In the performance of the duties devolving upon fire bosses, or certified persons acting as such, they shall have no superior officers, but all the employees working inside of such mine or mines shall be subordinate to them in their particular work.
No person shall enter such mine or mines for any purpose at the beginning of work upon shift therein until such signal or warning has been given by the fire boss or bosses as to the safety thereof, as by statute provided, except under the direction of the fire boss or bosses, and then for the purpose of assisting in making the mine safe: Provided, however, That miners regularly employed on a shift during which the mine is being preshift examined by a fire boss or certified person shall be permitted to leave or enter the mine in the performance of their duties.
Notwithstanding any other provision in this article contained, any person who holds a certificate issued by the Office of Miners' Health, Safety and Training certifying his or her competency to act as fire boss may perform the duties of a fire boss and any other duties, statutory or otherwise, for which he or she is qualified, in the same mine or section and on the same day or shift.
(a) In all mines, dangerous accumulations of fine, dry coal and coal dust shall be removed from the mine, and all dry and dusty operating sections and haulageways and conveyors and back entries shall be rock dusted or dust allayed by other methods as may be approved by the director.
(b) All mines or locations in mines that are too wet or too high in incombustible content for a coal dust explosion to initiate or propagate are not required to be rock dusted during the time any of these conditions prevail. Coal dust and other dust in suspension in unusual quantities shall be allayed by sprinkling or other dust allaying devices.
(c) In all dry and dusty mines or sections thereof, rock dust shall be applied and maintained upon the roof, floor and sides of all operating sections, haulageways and parallel entries connected thereto by open crosscuts. Back entries shall be rock dusted. Rock dust shall be so applied to include the last open crosscut of rooms and entries, and to within forty feet of faces. Rock dust shall be maintained in a quantity that the incombustible content of the mine dust that could initiate or propagate an explosion shall not be less than eighty percent. The incombustible content of mine dust in return entries shall also be equal to or greater than eighty percent.
(d) Rock dust shall not contain more than five percent by volume of quartz or free silica particles and shall be pulverized so that one hundred percent will pass through a twenty mesh screen and seventy percent or more will pass through a two hundred mesh screen.
(e) If requested by the director, an operator shall provide records establishing the quantity of bulk and bag rock dust purchased for a period not to exceed the immediately preceding six months.
§22A-2-25. Roof control programs and plans; refusal to work under unsupported roof.
(a) Each operator shall undertake to carry out on a continuing basis a program to improve the roof control system of each coal mine and the means and measures to accomplish such system. The roof and ribs of all active underground roadways, travelways and working places shall be supported or otherwise controlled adequately to protect persons from falls of the roof or ribs. A roof control plan and revisions thereof suitable to the roof conditions and mining systems of each coal mine and approved by the director shall be adopted and set out in printed form before new operations. The safety committee of the miners of each mine where such committee exists shall be afforded the opportunity to review and submit comments and recommendations to the director and operator concerning the development, modification or revision of such roof control plans. The plan shall show the type of support and spacing approved by the director. Such plan shall be reviewed periodically, at least every six months by the director, taking into consideration any falls of roof or rib or inadequacy of support of roof or ribs. A copy of the plan shall be furnished to the director or his or her authorized representative and shall be available to the miners and their representatives.
(b) The operator, in accordance with the approved plan, shall provide at or near each working face and at such other locations in the coal mine, as the director may prescribe, an ample supply of suitable materials of proper size with which to secure the roof thereof of all working places in a safe manner. Safety posts, jacks, or other approved devices shall be used to protect the workmen when roof material is being taken down, crossbars are being installed, roof bolt holes are being drilled, roof bolts are being installed and in such other circumstances as may be appropriate. Loose roof and overhanging or loose faces and ribs shall be taken down or supported. When overhangs or brows occur along rib lines they shall be promptly removed. All sections shall be maintained as near as possible on center. Except in the case of recovery work, supports knocked out shall be replaced promptly. Apprentice miners shall not be permitted to set temporary supports on a working section without the direct immediate supervision of a certified miner.
(c) The operator of a mine has primary responsibility to prevent injuries and deaths resulting from working under unsupported roof. Every operator shall require that no person may proceed beyond the last permanent support unless adequate temporary support is provided or temporary support is not required under an approved roof control plan and absence of such support will not pose a hazard to the miners.
(d) The immediate supervisor of any area in which unsupported roof is located shall not direct or knowingly permit any person to proceed beyond the last permanent support unless adequate temporary support is provided or temporary support is not required under an approved roof control plan and absence of such support will not pose a hazard to the miners.
(e) No miner shall proceed beyond the last permanent support in violation of a direct or standing order of an operator, a foreman or an assistant foreman, unless adequate temporary support is provided or temporary support is not required under an approved roof control plan and absence of such support will not pose a hazard to the miner.
(f) The immediate supervisor of each miner who will be engaged in any activity involving the securing of roof or rib during a shift shall, at the onset of any such shift, orally review those parts of the roof control plan relevant to the type of mining and roof control to be pursued by such miner. (g) Any action taken against a miner due, in whole or in part, to his or her refusal to work under unsupported roof, where such work would constitute a violation of this section, is prohibited as an act of discrimination pursuant to section twenty-two, article one of this chapter. Upon a finding of discrimination by the appeals board pursuant to subsection (b), section twenty-two, article one of this chapter, the miner shall be awarded by the appeals board all reliefs available pursuant to subsections (b) and (c), section twenty-two, article one of this chapter.
(a) Generally. -- The method of mining followed in any coal mine shall not expose the miner to unusual dangers from roof falls.
(b) Roadways, intersections and arches. -- The width of roadways shall not exceed sixteen feet unless additional support is added cross sectional. During the development of intersections, the roof between the tangents of the arches in the entry or room shall be supported with artificial roof supports prior to the development of such intersections. All areas where the arch is broken shall be considered as having unsupported roof and such roof should have artificial roof supports installed prior to any other work being performed in the area.
(c) Examinations and corrections. -- Where miners are exposed to danger from falls of roof, face and ribs, the operator shall examine and test the roof, face and ribs before any work or machine is started, and as frequently thereafter as may be necessary to insure safety. When dangerous conditions are found, they shall be corrected immediately. A probe or probes for methane detectors shall be provided on each working section other than longwall sections and sections mined solely with contininuous miners with integral roof bolters.
(d) Roof bolt recovery. -- Roof bolts shall not be recovered where complete extraction of pillars is attempted, where adjacent to clay veins or at the locations of other irregularities, whether natural or otherwise, that induce abnormal hazards. Where roof bolt recovery is permitted, it shall be conducted only in accordance with methods prescribed in the approved roof control plan, and shall be conducted by experienced miners and only where adequate temporary support is provided.
An authorized representative of the director may require in any coal mine where the height of the coal bed permits that electric face equipment, including shuttle cars, be provided with substantially constructed canopies or cabs to protect the miners operating such equipment from roof falls and from rib and face rolls.
The use of underground mining equipment of a size that does not conform to the height of the seam being mined, which creates unsafe working conditions for the miner operating the equipment or others, is prohibited: Provided, That the addition of or use of sideboards on shuttle cars shall be permitted if the shuttle car is equipped with cameras: Provided, however, That shuttle cars with sideboards as manufactured by an equipment manufacturer shall be permitted to be used without the use of cameras if permitted by the director. The Board of Coal Mine Health and Safety shall promulgate such rules as are necessary to effectuate this section.
§22A-2-29. Use of authorized explosives; storage or use of unauthorized explosives.
Permissible explosives or permissible blasting devices only shall be used in blasting coal or other material in underground coal mines. It shall be unlawful to have, use or store any nonpermissible explosives or nonpermissible blasting devices in any coal mine or on the premises of the mine, without a permit from the director.

Surface magazines shall be constructed of incombustible materials, be reasonably bulletproof and with no metal or sparking material exposed inside the magazine. Surface magazines shall be provided with doors constructed of at least one-fourth inch steel plate lined with a two-inch thickness of wood or the equivalent, properly screened ventilators, and with no openings except for entrances and ventilation, and shall be kept locked securely when unattended. The area for a distance of at least twenty-five feet in all directions shall be kept free of materials of a combustible nature; suitable warning signs shall be erected, so located that a bullet passing directly through the face of the sign will not strike the magazine. The location of magazines shall be not less than two hundred feet from any mine openings, occupied buildings or public roads unless barricaded. If magazines are illuminated electrically, the lamps shall be of vapor-proof type, properly installed and wired, and smoking and open lights shall be prohibited in or near any magazine.
Individual containers used to carry permissible explosives or detonators shall be constructed of substantial, nonconductive materials, kept closed and maintained in good condition. When explosives or detonators are transported underground in cars moved by means of locomotives, ropes, or other motive power, they shall be in substantially covered cars or in special substantially built covered containers used specifically for transporting detonators or explosives. Any container used for transportation or storage of explosives shall be properly identified or marked. Explosives or detonators shall not be hauled into or out of a mine within five minutes preceding or following a man trip. Where explosives and detonators are transported underground by belts, they shall be handled in the following manner: In the original and unopened cases, in special closed cases constructed of nonconductive material, or in suitable, individual containers. Clearance requirements shall be a minimum of eighteen inches; stop controls shall be provided at loading and unloading points, and an attendant shall supervise the loading and unloading. Neither explosives nor detonators shall be transported on flight or shaking conveyors, mechanical loading machines, locomotives, scrapers, cutting machines, drill trucks, or any self-propelled mobile equipment. If explosives and detonators are transported in the same explosives car or in the same special container, they shall be separated by at least four inches of hardwood partition or the equivalent; the bodies of such cars or containers shall be constructed or lined with nonconductive material. No hand loader shall take into any mine any larger quantity of explosives or detonators than he may reasonably expect to use in any one shift.
Explosives and detonators stored underground shall be kept in section boxes or magazines of substantial construction with no metal exposed on the inside, and be located at least fifteen feet from roadways and power wires in a well rock-dusted location, protected from falls of roof. If not kept in separate boxes or magazines not less than five feet apart, they may be kept in the same box or magazine if separated by at least a four-inch hardwood partition or the equivalent. Not more than a forty-eight hour supply of explosives or detonators shall be stored underground in section boxes or magazines. These boxes or magazines shall be kept at least one hundred feet from the faces and out of the direct line of blasting.
(a) Only a certified "shot firer" designated by mine management shall be permitted to handle explosives and do blasting. Only electric detonators of proper strength fired with permissible shot firing units shall be used except under special permits as hereinafter provided, and drillholes shall be stemmed with at least twenty-four inches of incombustible material, or at least one half of the length of the hole shall be stemmed if the hole is less than four feet in depth, unless other permissible stemming devices or methods are used. Drillholes shall not be drilled beyond the limits of the cut, and as far as practicable, cuttings and dust shall be cleaned from the holes before the charge is inserted. Charges of explosives exceeding one and one-half pounds, but not exceeding three pounds, shall be used only if drillholes are six feet or more in depth. Ample warning shall be given before shots are fired, and care shall be taken to determine that all persons are in the clear before firing. Miners shall be removed from adjoining places and other places when there is danger of shots blowing through. No shots shall be fired in any place known to liberate explosive gas, until such place has been properly examined by a competent person who is designated by mine management for that purpose, and no shots shall be fired in any place where gas is detected with a permissible flame safety lamp until such gas has been removed by means of ventilation. After firing any shot, or shots, the person firing the same shall not return to the working face until the smoke has been cleared away and then he shall make a careful examination of the working face before leaving the place or before performing any other work in the place.
(b) Multiple shooting in coal or rock or both is authorized only under permit issued by the director.

Each operator shall maintain the concentration of respirable dust in the mine atmosphere during each shift to which miners in active workings of such mine are exposed below such level as the board may establish. The board may promulgate rules governing respirable dust, including, but not limited to, dust standards, sampling procedures, sampling devices, equipment and sample analysis by using the data gathered by the federal Mine Safety and Health Administration and, or the federal Bureau of Mines.
Any operator found to be in violation of such standards shall bring itself into compliance with such standards and rules of the board or the director may thereafter order such operator to discontinue such operation.
(a) Before a coal operator conducts underground mining operations within five hundred feet of any well, including the driving of an entry or passageway, or the removal of coal or other material, the coal operator shall file with the Office of Miners' Health, Safety and Training and forward to the well operator by certified mail, return receipt requested, its mining maps and plans (which it is required to prepare, file and update to and with the regulatory authority) for the area within five hundred feet of the well, together with a notice, on a form furnished by the director, informing them that the mining maps and plans are being filed or mailed pursuant to the requirements of this section.
Once these mining maps and plans are filed with the office, the coal operator may proceed with its underground mining operations in the manner and as projected on such plans or maps, but shall not remove, without the consent of the director, any coal or other material or cut any passageway nearer than two hundred feet of any completed well or well that is being drilled. The coal operator shall, at least every six months while mining within the five hundred foot area, update its mining maps and plans and file the same with the director and the well operator.
(b) Application may be made at any time to the director by a coal operator for leave to conduct underground mining operations within two hundred feet of any well or to mine through any well, by petition, duly verified, showing the location of the well, the workings adjacent to the well and the mining operations contemplated within two hundred feet of the well or through such well, and praying the approval of the same by the director and naming the well operator as a respondent. The coal operator shall file such petition with the director and mail a true copy to the well operator by certified mail, return receipt requested.
The petition shall notify the well operator that it may answer the petition within five days after receipt, and that in default of an answer the director may approve the proposed operations as requested if it be shown by the petitioner or otherwise to the satisfaction of the director that such operations are in accordance with the law and with the provisions of this article. If the well operator files an answer which requests a hearing, one shall be held within ten days of such answer and the director shall fix a time and date and give both the coal operator and well operator five days' written notice of the same by certified mail, return receipt requested. At the hearing, the well operator and coal operator, as well as the director, shall be permitted to offer any competent and relevant evidence. Upon conclusion of the hearing, the director shall grant the request of the coal operator or refuse to grant the same, or make such other decision with respect to such proposed underground operation as in its judgment is just and reasonable under all circumstances and in accordance with law and the provisions of this article: Provided, That a grant by the director of a request to mine through a well shall require an acceptable test to be conducted by the coal operator establishing that such mining through can be done safely.
If a hearing is not requested by the well operator or if the well operator gives, in writing, its consent to the coal operator to mine within closer than two hundred feet of the specified well, the director shall grant the request of the coal operator within five days after the petition's original five day answer period if the director determines that such operations are just, reasonable and in accordance with law and the provisions of this article.
The director shall docket and keep a record of all such proceedings. From any such final decision or order of the director, either the well operator or coal operator, or both, may, within ten days, appeal to the circuit court of the county in which the well subject to said petition is located. The procedure in the circuit court shall be substantially as provided in section four, article five, chapter twenty-nine-a of this code, with the director being named as a respondent. From any final order or decree of the circuit court, an appeal may be taken to the Supreme Court of Appeals as heretofore provided.
