PART IIIUnderground Transportation and Hoisting (continued)
(2) Subject to subsection 89(2), the couplings of a cage or mine car shall be used only in conjunction with safety chains or safety ropes that are of sufficient strength to hold the maximum load for which the cage or mine car is designed in the event that the coupling chain breaks.
(3) Every draw-bar of a three-draw-bar man car and every coupling, pin, safety chain, rope clamp and other tackling equipment that is used on a cage or mine car shall be made of steel.
(4) The steel referred to in subsection (3) shall be
(5) The employer shall keep a record of the heat treatment referred to in paragraph (4)(b) at the coal mine in which the equipment that is heat treated is used.
(6) No draw-bar, coupling, pin, safety chain, rope clamp or other tackling equipment shall be used on a cage or mine car unless
(a) its design has been tested by the manufacturer to withstand a proof load of 40 per cent of its breaking strength without any permanent set;
(b) a certificate of the test referred to in paragraph (a) has been provided to the employer by the manufacturer; and
(c) the equipment has been legibly and permanently marked to identify it with the manufacturer’s certificate.
(2) Safety chains and safety ropes shall be designed with a factor of safety of not less than two.
(3) Draw-bars that are manufactured from steel that is certified by the manufacturer not to require heat treatment to remove stresses that are due to cold working shall be designed with a factor of safety of not less than six.
(4) Draw-bars that are manufactured from steel that requires heat treatment every six months to remove stresses that are due to cold working and draw-bars that are made of rolled steel sections and plates shall be designed with a factor of safety of not less than 10.
(5) Subsections (1) to (4) apply on and after October 1, 1993.
Operation and Inspection of Mine Cars
(2) No person shall get into or out of a trip while it is in motion.
(3) Before a mine car is detached from its rope or locomotive and is parked on an incline, its wheels shall be sampsoned and braked or shall be spragged.
91 (1) At least once every day of operation of a coal mine, a qualified person shall inspect the couplings, pins, safety chains, draw-gear, rope clamps and safety brakes of all mine cars in use on gradients exceeding four per cent.
(2) At least once every month, a qualified person shall test the overspeed governor referred to in paragraph 84(3)(c).
(3) At least once every three months, a qualified person shall carry out a dynamic test on the safety brake system referred to in subsection 84(3).
(4) The qualified person referred to in subsections (1) to (3) shall make a record of each inspection and test carried out by the person in a book kept for that purpose.
92 At least once every three months, the position of the clamps that attach a trip to the hoist rope on an endless hoist rope system shall be moved to a new point of attachment that is at a distance of not less than the maximum length of the trip, and each movement of the position shall be made in the same direction along the hoist rope.
Vertical Shafts and Airways
93 Every opening to a vertical shaft or to an airway that is used only for ventilation shall be fenced.
94 Every vertical shaft that is a working shaft shall be provided with stops or gates that prevent a cage or mine car from being pushed unintentionally beyond the landings of the shaft.
95 All landings of vertical shafts that are working shafts shall be lighted with permanent light fixtures.
(2) The mine manager shall establish a code of signals for the purposes of subsection (1).
(3) The employer shall post a copy of the code referred to in subsection (2) in a conspicuous place at all locations where a means of communication is provided.
Safe Operating Procedures for Transporting Persons
97 Where a cage or mine car in a vertical shaft is used for transporting persons and is also used for transporting materials, the cage or mine car shall not be used for transporting persons at the same time as materials are being transported.
(2) Subject to subsection (3), no person shall be transported underground at a speed greater than 6 m/s unless
(3) No person shall be transported underground at a speed greater than the speed for which the cage or mine car is designed.
Standards for Diesel Equipment
99 Every diesel engine that is used underground shall be fitted with an inlet and exhaust-flame trap.
(2) The procedures referred to in subsection (1) shall specify
(a) the location and method of refuelling the locomotives and engines;
(b) that no operator of a diesel engine shall leave it unattended while the engine is running; and
(c) that there shall always be an adequate supply of dry sand to enable the diesel locomotive to complete any journey that it begins.
101 The employer shall submit a copy of the procedures referred to in subsection 100(1) and any changes in those procedures to the Coal Mining Safety Commission for approval at least 30 days before the implementation of the procedures or changed procedures.
102 No person shall operate a diesel locomotive in any underground portion of a coal mine unless the person
(a) has at least one year’s experience in a coal mine of which at least 90 days have been spent in work associated with the undergound operation of a diesel locomotive; and
(b) is trained and authorized to operate the diesel locomotive in that portion of the coal mine.
Maintenance, Inspection and Tests
(2) The qualified diesel mechanic referred to in subsection (1) shall make a written report of the results of each inspection and supervision made by the mechanic in a book kept for that purpose.
(2) The qualified person referred to in subsection (1) shall make a written report of the results of each inspection and test made by the person in a book kept for that purpose.
