Inconsistent Provisions

 In the event of an inconsistency between any standard incorporated by reference in a provision of these Regulations and any other provision of these Regulations, that other provision shall prevail to the extent of the inconsistency.


 Before an employee is employed in a position of mine manager or is appointed to a position of underground manager or overman, the employee shall have obtained the qualifications required for all positions junior to that position.

Appointments and Supervision

  •  (1) No explosive or detonator shall be stored underground in a coal mine.

  • (2) Explosives and detonators that are intended for use underground shall be stored in a structure above ground that has been approved by the Coal Mining Safety Commission.

  • (3) The maximum quantity of explosives and detonators that are stored in accordance with subsection (2) shall be not more than the quantity required for use underground during the 24-hour period immediately following its storage.

  • (4) Detonators shall be stored separately from explosives in a room that has a wall of masonry not less than 150 mm thick between it and any room in which explosives are stored.

  •  (1) All explosives and detonators that are transported underground, other than explosives and detonators referred to in subsection 28(3) or 29(4), shall be in secure cases or canisters with the detonators in separate cases or canisters from the explosives.

  • (2) No case or canister referred to in subsection (1) shall contain more than 5 kg of explosive unless approval for the transportation of the explosive in bulk has been given by the Coal Mining Safety Commission.

  •  (1) Every employee who receives, transports or uses explosives or detonators shall return any explosive or detonator that is not used during the employee’s shift to the surface structure in which it had been stored.

  • (2) Where an explosive or detonator is transported underground, it shall be kept in its secure case or canister until it is used.

  • (3) Subject to subsection (4), each case or canister referred to in subsection (2) shall be kept separate from every other case or canister and from all equipment that is likely to cause the ignition of the explosive or the detonator, by as great a distance as is practicable in the area where the explosive or detonator is kept.

  • (4) The distance referred to in subsection (3) shall be not less than 300 mm.

  •  (1) A qualified person shall have control of the storage, issue and receipt of all explosives and detonators.

  • (2) The qualified person referred to in subsection (1) shall

    • (a) test each detonator for electrical continuity before issuing it;

    • (b) issue detonators to no person other than a shotfirer; and

    • (c) receive and store unused explosives and detonators returned from underground.

Care of Blasting Machines

  •  (1) A qualified person shall, at least once every three months, clean and thoroughly overhaul all blasting machines that are in service.

  • (2) A record of the work performed pursuant to subsection (1) shall be made by the qualified person who performed the work.


  •  (1) No person other than a shotfirer shall fire a shot.

  • (2) 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.

Shotfiring Procedures

 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.

  • (2) No shot shall be fired

    • (a) in broken coal or in a support pillar; or

    • (b) in an area where the concentration of flammable gas in the air exceeds 1.25 per cent.

  • (3) Every coal-cutting machine shall be stopped before shots are fired at the return brushing face in a longwall section.

Preparations Before Charging a Shot Hole

 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,

  • (a) 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;

  • (b) examine the shot hole to verify that it has been thoroughly cleaned;

  • (c) verify that the shot hole does not intersect any cracks or crevices greater than 3 mm;

  • (d) verify that the shot hole is at least 3 mm larger than the diameter of the cartridge of the explosive to be used;

  • (e) place a plug of stemming in the back of the shot hole; and

  • (f) 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.
