Regulation 371The manager of a mine shall ensure that,(a) cables used in the mine comply with the requirements of the applicable standards prescribed under these Regulations, or with the directions of the Chief Inspector of Mines;(b) cables in the mine are installed, located and maintained so as(i) not to obstruct access ways;(ii) to minimise the risk of damage being caused to the cable; and(iii) to separate the cable from other services in the mine;(c) cables installed in a part of the mine where quarrying operations are undertaken, or in an underground mine or on a dredge in the mine, are protected by a metallic or steel wired armoured XLPE or PBC/SWA/PBC covering that (i) is electrically continuous;(ii) is connected to earth;(iii) is protected against corrosion;(iv) is securely attached to equipment at each end; and (v) encloses the conductors of the cable including the earthing cable;(d) cables installed in the ground in the mine which operate at a voltage exceeding extra-low voltage are(i) installed in accordance with applicable standards prescribed under these Regulations, or with directions issued by the Chief Inspector;(i) installed with orange cable marker tape;(iii) where necessary to ensure that, so far as is practicable, persons are not exposed to hazards, installed with surface cable route indicators; and(iv) where there is a material risk of the cable being disturbed by a man-made ground disturbance or where the cable is located in a traffic area, protected by either steel wire armour, if buried directly in the ground, or a substantial heavy duty wiring enclosure;(e) excavation work is not carried out in the vicinity of buried cables in the mine unless, prior to the commencement of that work, an assessment is made of the measures that should be employed to ensure that, as far as is practicable, that work does not expose persons to hazards and that work is carried out consistently with those measures;(f) the exposed ends of cables in the mine, where the cables enter the terminals of switches, fuses or other appliances are protected and finished off in a manner that ensures that(i) moisture cannot creep along the insulating material within the waterproof sheath; and (ii) the insulating material, if of an oily nature, cannot leak out of the cable;(g) small wires for lighting circuits in the mine are appropriately (i) insulated, encased, protected and fixed; or(ii) tied or suspended;(h) metallic pipes used in the mine are electrically continuous and earthed;(i) separate uncased wires used in the mine are kept at least five centimetres apart and not brought together except at lamps, switches or other fittings;(j) wires are suspended or fixed using materials designed for that purpose;(k) each cable used in a shaft is(i) highly insulated and substantially fixed; and(ii) where it is not capable of sustaining its own weight, properly supported at intervals varying according to the weight of the cable;(l) where a cable used in a shaft in the mine is not completely boxed in and protected from any falling material, the cable  is placed in a manner that leaves sufficient space between the cable and the side of the shaft that enables the cable to yield to, and lessen, the impact of the falling material;(m) a cable in a shaft in the mine is not fixed in a winding compartment;(n) a cable in a drive or road in the mine along which any material is conveyed that cannot be kept at least thirty centimetres from any part of a truck or tram is specially protected;(o) cables and wires in the mine, unless provided with metallic coverings, are not fixed to walls or timbers by means of metallic fastenings;(p) where repairs are being carried out or blasting is being done in a drive or road, suitable protection is provided for any cable in the drive or road;(q) each overhead bare wire on the surface of the mine is (i) properly secured to insulators;(ii) except in the case of a wire carrying a voltage that does not exceed low voltage, provided with efficient lightning arrestors; and(iii) clear of all traffic with a minimum ground clearance which as far as is practicable, minimise hazards and is not less than five and a half metres;(r) each joint made in any cable at the mine is mechanically and electrically efficient and is suitably soldered where reasonably practicable;(s) when shot-firing cables or wires are used in the vicinity of power or lighting cables in the mine, every precaution is taken to prevent the shot-firing cables or wires from coming into contact with the lighting or power cables; and(t) electricity from lighting or power cables in the mine is not used for firing shots.(2) Paragraph (c) of sub-regulation (1) does not apply to (a) a trailing or reeling cable;(b) a cable or conductor energised at a voltage not exceeding extra-low voltage;(c) a flexible conductor which exceeds three metres in length and which is permanently connected to a portable apparatus;(d) a cable used in a floating treatment as part of a dredging operation; or(e) a cable used for telephone or signalling purposes.(3) The manager of a mine shall ensure that cables that supply electrical power in the mine from surface to underground are fed with electrical voltage not higher than a low voltage except for the purposes of transmission.
