The distance referred to in subsection (3) shall be not less than 300 mm. A qualified person shall have control of the storage, issue and receipt of all explosives and detonators. The qualified person referred to in subsection (1) shall test each detonator for electrical continuity before issuing it; issue detonators to no person other than a shotfirer; and receive and store unused explosives and detonators returned from underground. A qualified person shall, at least once every three months, clean and thoroughly overhaul all blasting machines that are in service. A record of the work performed pursuant to subsection (1) shall be made by the qualified person who performed the work. No person other than a shotfirer shall fire a shot. No shotfirer shall fire a shot unless the shotfirer has been authorized to fire that type of shot. The handling of explosives and detonators in the preparation underground of a shot or shot hole shall be under the direct supervision and control of a shotfirer. Where shotfiring is to be done underground during a shift, the shotfirer shall verify that no more explosives or detonators than are required for the shotfiring are kept in the danger area referred to in paragraph 22(1)(a) in which the shotfiring is to be done. A shotfirer shall use only one class, grade or quality of explosive in a shot; an explosive that is in its original wrapping; no more explosive in any shot hole than the amount that is necessary for the work to be performed or the maximum amount of that type of explosive that is set out in column II of Part I of Schedule II, whichever is the lesser; tamping rods and stemmers that are constructed of non-metallic materials; and a cleaner and crack detector that is capable of cleaning the full length of the shot hole and detecting transverse and longitudinal cracks of 3 mm or more in the shot hole. No shot shall be fired in broken coal or in a support pillar; or in an area where the concentration of flammable gas in the air exceeds 1.25 per cent. Every coal-cutting machine shall be stopped before shots are fired at the return brushing face in a longwall section. Before initiating the preparations for charging a shot hole referred to in section 21, a shotfirer shall verify that all broken coal is removed from the area of the shot hole and shall allow sufficient time for dust in the air to settle. A shotfirer shall, immediately before charging a shot hole underground, subject to subsection 27(3), verify, using a methanometer and a locked-flame safety lamp, that the concentration of flammable gas in the general body of the air in the area of the shot hole and in any area contiguous thereto does not exceed 1.25 per cent; examine the shot hole to verify that it has been thoroughly cleaned; verify that the shot hole does not intersect any cracks or crevices greater than 3 mm; verify that the shot hole is at least 3 mm larger than the diameter of the cartridge of the explosive to be used; place a plug of stemming in the back of the shot hole; and verify that any dust in the area of the shot hole has been treated with stone dust to a minimum of three 25 kg bags of stone dust per metre of advance. Before firing a shot, a shotfirer shall determine a danger area that extends at least 30 m from the shot hole; evacuate all persons from the danger area; and post sentries at the limits of the danger area. The sentries referred to in paragraph (1)(c) shall prevent any person, other than the shotfirer, from entering the danger area until the shotfirer verifies that the area is safe to enter. No person, other than a shotfirer, shall enter the danger area referred to in subsection (1) until the person has been informed by the shotfirer or a sentry that it is safe to do so. Immediately before firing a shot, a shotfirer shall repeat the test referred to in paragraph 21(a). Where a shot or round of shots is fired, the shotfirer shall make an examination of the effect of the shot or round of shots before the next shot or round of shots is fired. Where a shot is to be fired with a blasting machine, the shotfiring cable shall be not less than 30 m long. No person, other than a shotfirer, shall connect a shotfiring cable to detonator wires or to a blasting machine. Where a shot is to be fired with a blasting machine, the shotfirer shall, in the following sequence, twist the ends of the shotfiring cable together at the blasting machine and isolate them from ground; check the shotfiring cable and the detonator circuit; connect the shotfiring cable to the shot; check the total circuit; verify that all persons in the danger area referred to in paragraph 22(1)(a) have been evacuated from that area; connect the shotfiring cable to the blasting machine, verifying that the shotfirer alone has possession and control of the blasting machine; shout “FIRE” or “TIR”; verify that the danger area referred to in paragraph 22(1)(a) is clear of persons; take cover outside the danger area referred to in paragraph 22(1)(a); fire the shot; subject to sections 28 and 29, wait at least five minutes before the shotfirer returns to the area of the shot hole to satisfy himself that no dangerous condition has resulted from firing the shot; and measure the concentration of flammable gas in the general body of the air in the area of the shot hole. Subject to section 27, each shot hole shall be charged separately and each shot shall be fired singly. Subject to subsections (2) to (4), rounds of shots may be fired in shafts, development drivages, cross-measure drivages, intake and return brushings of longwall faces and repair brushings. Not more than 12 shots in a round may be fired simultaneously using the shortest millisecond-delay detonators. A round of shots using different millisecond-delay detonators shall not be fired unless the concentration of flammable gas in the general body of the air in the area of the shot holes and in any area contiguous thereto does not exceed where the period between the detonation of the first shot and the detonation of the last shot is calculated not to exceed 0.2 second, 1 per cent, and where the period between the detonation of the first shot and the detonation of the last shot is calculated to exceed 0.2 second but not to exceed 0.75 second, 0.8 per cent; the mine manager has issued to the shotfirer for each area of firing a copy of the shotfiring pattern that shows the position and direction of every shot hole in the round, the maximum quantity of explosive to be used in each shot hole, and the maximum length of each shot hole; and the maximum period that may elapse between the detonation of the first shot and the detonation of the last shot is where the shots are fired in a development drivage that contains no seam of coal exceeding 300 mm and that is more than 5 m from a waste or fault, 0.75 second or less, and in all other cases, 0.2 second or less. A copy of the shotfiring pattern for each area at which multi-shot firing is carried out in a mine shall be kept available above ground at the coal mine for examination by employees. Where a single shot misfires, the shotfirer shall, in the following sequence, remove the handle or key from the blasting machine and disconnect the blasting machine from the shotfiring cable; wait 15 minutes; examine the shotfiring cable and connections for any defects and remedy any that are found; and make a further attempt to fire the shot using either the same blasting machine or another blasting machine that is suitable for the purpose. Where the attempt to fire the shot referred to in paragraph (1)(e) fails, the shotfirer shall, in the following sequence, mark the location of the detonator lead wires of the misfired shot; cause a new shot hole to be drilled at a distance of not less than 300 mm from the loaded shot hole and parallel to and equal in depth to that shot hole; and fire a shot in the newly drilled shot hole. A shotfirer shall wait for five minutes after firing the shot referred to in paragraph (2)(f) and then, where practicable, sort the debris by hand, recover all explosives and detonators from the debris and take them to the structure referred to in subsection 11(2). Where all of a round of shots misfire, the shotfirer shall, in the following sequence, remove the handle or key from the blasting machine and disconnect the shotfiring cable from the blasting machine; test the circuit for electrical continuity; and if the test shows that there is electrical continuity, attempt to fire the round using either the same blasting machine or another blasting machine that is suitable for the purpose. Where the test referred to in paragraph (1)(e) shows that there is no electrical continuity, or where the attempt referred to in that paragraph fails, the shotfirer shall, in the following sequence, wait 15 minutes; disconnect the shotfiring cable and detonator lead wires at each shot hole; test for electrical continuity in the shotfiring cable and detonator lead wires; test the blasting machine; and if the tests show that there is electrical continuity, the detonator lead wires and the shotfiring cable shall be reconnected and tested for electrical continuity and a further attempt shall be made to fire the round. Where any of the tests referred to in paragraphs (2)(e) to (g) do not produce the desired result, the shotfirer shall install barricades and post a warning sign in accordance with subsection 31(1). Where a single shot in a round misfires and is recovered, or where a part of a round of shots misfires and is recovered, the shotfirer shall sort the debris by hand, recover all explosives and detonators from the debris and take them to the structure referred to in subsection 11(2). Where a single shot in a round misfires and is not recovered, the procedures set out in subsections 29(1) and (2) shall be carried out. Where a part of a round of shots misfires and is not recovered, the procedures set out in subsection 29(2) shall be carried out and groups of shots with the same millisecond-delay shall be fired in turn, in increasing order of delay. Where a misfired shot is not recovered, the shotfirer shall cause barricades to be installed to prevent persons from entering the danger area for the shot hole determined in accordance with paragraph 22(1)(a); and a warning sign to be conspicuously posted on each barricade referred to in paragraph (a) with the words “MISFIRED SHOT — KEEP OUT” and “COUP DE MINE RATÉ — ENTRÉE INTERDITE”. After having carried out the procedures set out in subsection (1), the shotfirer shall report orally to the underground manager or mine manager the misfired shot and the procedures carried out. Where a shot flames on firing, the shotfirer shall, in the following sequence, immediately take steps to extinguish the flame; verify that the section of the coal mine in which the shot was fired is guarded by an employee and left unworked, except for making the section safe, until inspected by a safety officer; without delay, report the flamed shot orally to the shotfirer’s supervisor or the underground manager; and report the flamed shot in writing to the mine manager. Where a mine manager is informed of a flamed shot in accordance with paragraph (1)(d), the mine manager shall, without undue delay, make a report of the flamed shot to a safety officer at the district office. At the end of a shotfirer’s shift, the shotfirer shall report in writing to the shotfirer’s immediate supervisor every misfired shot and flamed shot for which the shotfirer was responsible during the shift. Where an immediate supervisor is informed of a misfired shot or flamed shot in accordance with subsection (1), the supervisor shall, without undue delay, report in writing to the underground manager or mine manager the misfired shot or flamed shot. At the end of a shotfirer’s shift, the shotfirer shall record in a book that is kept for that purpose all the shots the preparation and firing of which the shotfirer was responsible for during the shift. The record referred to in subsection (1) shall include the number of detonators used; the amount of explosive used, expressed in grams; in respect of each shot or round of shots, the time of firing of the shot or round of shots, the concentration of flammable gas in the air before and after each shot or round of shots was fired, the number of detonators used, and the number of misfired shots and whether they were recovered; and the number of flamed shots. The mine manager shall, in respect of each underground portion of a coal mine, develop for employees procedures for the safe entry to, exit from and occupancy of that portion; develop emergency procedures that include an emergency evacuation plan, a description of the procedures to be followed, the location of the emergency equipment provided by the employer, and an up-to-date plan of the coal mine; and develop and implement safe operating procedures for each employee occupation. The employer shall keep a copy of the procedures referred to in subsection (1) readily available for examination by employees at the coal mine in respect of which the procedures apply. The employer shall instruct and train all employees in the procedures referred to in paragraphs (1)(a) and (b).

A shaft may be connected to another shaft by a passageway if the passageway is not less than 1.2 m in width and 1.2 m in height. A qualified person shall, every day, inspect the vertical shafts by which employees descend or ascend in a coal mine; and all shaft equipment that is used in the transportation system for employees in the vertical shafts. The qualified person referred to in subsection (1) shall make a written report of the inspection in a book kept for that purpose. A mine manager shall define on a plan, on a scale of not less than 1:10,000, the limits of each section of the mine for which an overman is responsible in such a manner that every working face, other than an area where work is being carried out for the purpose of repairing or enlarging a roadway, is included within a section; and the section is of a size that permits a pre-shift inspection to be completed in two hours or less. A mine manager shall designate a meeting station that is located at the entrance to each overman’s section referred to in subsection (1) and shall mark each meeting station clearly on the plan; and cause a notice to be posted at each meeting station identifying it as a meeting station. No person, other than a person carrying out an inspection or a person accompanying that person, shall pass beyond a meeting station referred to in subsection (2) unless the section has been inspected and reported to be safe by the person who carried out the inspection referred to in subsection 41(1); and the person is instructed to pass beyond the meeting station by the overman responsible for the section. No overman shall instruct any person to pass beyond the meeting station of the section for which the overman is responsible unless the overman has information indicating that it is safe to pass beyond the meeting station. Every overman’s section shall be inspected by a mine examiner within the four-hour period preceding the beginning of work by each shift in that section. Where there are persons present in an overman’s section, a mine examiner shall carry out the inspections of that section at intervals not exceeding eight hours. Every overman who is responsible for a section shall inspect every part of the section at least once during every shift at such times that no place at which an employee works remains uninspected by the overman for more than four hours after the timewhen the shift of that employee began work in that section. The inspection referred to in subsection (1) shall be carried out to ascertain the conditions in relation to ventilation, strata control and general safety.

Where an auxiliary fan stops, no person shall restart the auxiliary fan unless a qualified person has inspected the area underground that is serviced by the auxiliary fan and has tested for flammable gases; and informed the person that it is safe to restart the auxiliary fan. The mine manager shall prepare procedures to be followed in the event of the stoppage of an auxiliary fan and shall post a copy of those procedures in a conspicuous place at the surface of the coal mine. All main fans and booster fans and associated equipment shall be inspected by a qualified person at intervals of not more than 30 minutes. Every qualified person who inspects a main fan, a booster fan or any associated equipment shall be authorized to do so and shall hold a certificate as a mine mechanic or a mine electrician. Every qualified person who inspects a main fan, a booster fan or any associated equipment shall record the results of the inspection in a book kept for that purpose. For every portion of a coal mine, the mine manager shall prepare and keep up to date written procedures for ventilation surveys. The procedures referred to in subsection (1) shall include a requirement for a volumetric ventilation survey to be made in every underground portion of the coal mine at least once every month; and be certified by an engineer. The mine manager shall submit a written report of each ventilation survey made in accordance with the procedures referred to in subsection (1) to a safety officer at the district office within 15 days after the end of the month in which the ventilation survey is made. Where the quality or quantity of air underground is not in accordance with subsection 110(1), the mine manager shall, without delay, take measures to correct the deficiency. Immediately before the beginning of every shift and at least once every day, the barometric pressure and temperature out of doors above ground at a coal mine shall be measured and recorded by a qualified person or by mechanical means. The mine manager shall, within 24 hours after the making of a record referred to in subsection (1), countersign the record or a copy thereof. Immediately after the taking of a measurement referred to in subsection 121(1), a notice shall be posted in a conspicuous place in the lamp house setting out the barometric pressure and the trend of the barometric pressure at the time of the posting of the notice. The notice referred to in subsection (1) shall be kept posted until it is replaced by a notice of a subsequent measurement. A qualified person who holds a certificate as a mine examiner and carries a locked-flame safety lamp shall inspect at least once every seven days all shafts, other than shafts that are used solely for ventilation, and all accessible stoppings underground; inspect at least once every seven days the bottom and top of each shaft that is used solely for ventilation; and make a written report of each inspection referred to in paragraphs (a) and (b) to the underground manager. The report referred to in paragraph (1)(c) shall set out the date and time of the inspection; a statement as to the condition of the airways and accessible stoppings; and the qualified person’s safety observations respecting the roof support, ventilation, stone dust and accumulations of water and concentrations of flammable or noxious gases in the airways and accessible stoppings. A qualified person shall, at least once every seven days and whenever any alteration is made in the ventilation system serving a roadway on which a diesel engine is operated measure the quantity of air passing over the roadway; measure the concentration of flammable gas in the air in the roadway, using a methanometer; measure the concentration of flammable gas in the air at the ends of the roadway and at a point 10 m from the downwind end of the diesel engine, using a methanometer; measure the concentration of carbon monoxide in the air at a point 10 m from the downwind end of the diesel engine, using a carbon monoxide detector; and record the measurements referred to in paragraphs (a) to (d) in a book kept for that purpose. A sample of the undiluted exhaust gas from every diesel engine that is operated underground shall be taken and analysed at least once every month. Where a sample referred to in subsection (1) contains more than 2,000 ppm of carbon monoxide, the diesel engine shall be removed from service underground. The employer shall record the result of each analysis referred to in subsection (1) in a book kept for that purpose. The mine manager shall designate the location and frequency of tests underground for flammable gas in such a manner that dangerous concentrations of gas are detected in time for corrective measures to be taken; and where necessary, employees to be evacuated safely and expeditiously. Where an employee is required under these Regulations to test for flammable gas, the employer shall provide the employee with a methanometer that is capable of testing for flammable gas in layers, cracks, crevices and other locations that are normally beyond arm’s reach. Every employee who tests for flammable gas shall make a record of each test in a book kept for that purpose. Where six consecutive measurements, taken in accordance with the procedures for ventilation surveys referred to in subsection 119(1) at a location underground where electrical machinery or electrical equipment is used, show a concentration of flammable gas that exceeds 0.5 per cent, a methanometer shall be installed at the location. Where an electrical machine or electrical equipment is operated at a longwall face, a methanometer shall be installed at each end of the face and one of those methanometers shall be installed as near to the return brushing face as is practicable. Where the concentration of flammable gas exceeds 0.8 per cent in a location underground where electrical equipment or a diesel engine is operated or where a source of ignition is present, a test for gas shall be made in that location, using a methanometer, at least once every eight hours for as long as the concentration of flammable gas exceeds 0.8 per cent. Where the concentration of flammable gas at the return end of a longwall face may exceed 1.25 per cent, the employer shall provide, at appropriate locations, a methanometer that automatically displays a visual indication of the concentration and sounds an audible alarm to warn employees working at or near the longwall face when the concentration exceeds 1.25 per cent. Where the concentration of flammable gas in the air in an underground portion of a coal mine exceeds 1.25 per cent, the following procedures shall be followed: during the period in which the concentration exceeds 1.25 per cent, the operation of all diesel engines and of all electrical equipment that is not intrinsically safe, other than electric safety lamps, shall be stopped in that portion of the coal mine; and the employer shall, within seven days, make a written report of that concentration of flammable gas to a safety officer at the district office. Where the concentration of flammable gas in the air in an area underground exceeds 2 per cent, all persons shall forthwith be evacuated from the area to a place that is ventilated in accordance with subsection 110(1). Where an area has been evacuated in accordance with subsection (1), a warning sign bearing the words “DO NOT ENTER” and “ENTRÉE INTERDITE” shall be posted in a conspicuous place at the entrance to the area; and no person, other than an authorized person, shall enter the evacuated area unless the authorized person has informed the person that it is safe to enter. Methanometers at the intake and return ends of a longwall face shall be designed to continually measure the concentration of flammable gas in the air; display the concentration of flammable gas; and record the concentration of flammable gas. The record referred to in paragraph (1)(c) shall be displayed where the concentration is recorded remotely, for a period of at least 24 hours after it is made; and in any other case, for a period of at least two hours after it is made. Where remote monitoring of flammable gas is carried out, there shall be a qualified person at the remote monitoring station at all times. The mine manager shall establish and keep at the remote monitoring station procedures to be followed by a qualified person referred to in subsection (3) whenever an audible alarm is sounded. Every area underground shall be kept free from accumulations of coal dust. Dry areas underground in which coal dust is produced shall be systematically wetted down with water. To reduce coal dust underground, where dry coal is cut by a coal-cutting machine, a jet of water shall be directed over the picks of the machine; and mined coal shall be kept wet during handling. Every roadway underground shall be treated with incombustible dust in such a way that the dust on the floor, roof and sides of the roadway contains where the concentration of flammable gas in the air in the roadway does not exceed 1 per cent, not less than 75 per cent by weight of incombustible dust; and where the concentration of flammable gas in the air in the roadway exceeds 1 per cent, not less than 80 per cent by weight of incombustible dust. Subject to subsection (3), the incombustible dust referred to in subsection (1) shall contain not less than 70 per cent by weight of fine material that is capable, when dry, of passing through a sieve of 200 mesh. Where a larger percentage of incombustible dust than the percentage referred to in subsection (1) is used, the percentage of fine material referred to in subsection (2) may be reduced in proportion to the increase in the amount of incombustible dust, but in no case shall it be less than 25 per cent. At least once every month, samples of dust shall be taken from the floor, roof and sides along the length of each roadway underground and shall be analysed to determine the percentage of combustible material therein. The employer shall, in respect of the analysis referred to in subsection (1), keep a record of the analysis; and submit a written report of the results of the analysis to a safety officer at the district office before the 15th day of the month following the analysis.
