Specifies requirements for the design, construction and testing of electric motor-driven coal-mining machinery and accessories intended for use in explosive atmospheres of underground coal mines. It covers both battery-operated and mains-powered machines and includes requirements for lighting systems, gas monitoring, electrical protection, enclosures, interlocking, wiring, motors and transformers. Requirements covering the longwall method of mining are included.

This Standard specifies requirements for the design, construction and testing of electric motor-driven coal mining machines (including longwall machines), hereinafter referred to as electrical machines, and accessories intended for use in hazardous areas in and around underground coal mines.NOTE: Mining machines and accessories may require approval by the relevant regulatory authority. Enquiries concerning approval may be made to the following: Department of Mineral Resources, N.S.W.Department of Resource Industries, QldDepartment of Mines, Tas.Department of Mines, W.A.Department of Mines and Energy, S.A.Department of Industry, Technology and Resources, Vic.
