25、riteria of remote control systems for mining equipmentand machinery. It also recommends safeguarding practices and the provision for trainingof personnel associated with the operation and maintenance of such equipment andmachinery.It applies to systems where the remote controls are located with the
26、operator who remainsin visual and audible range of the equipment or machine being controlled. Typical systemsof remote control may incorporate, but are not limited to, radio or infra-red transmittersand receivers or direct electrical, hydraulic and pneumatic connections.1.2 APPLICATION This Standard
27、 applies to remotely controlled mining equipmentand machines including breaker line supports, continuous miners, flexible conveyor trains,load-haul-dumps, longwall supports and shearers, shovels and shuttle cars.It applies to coal and metalliferous mining machines used in both surface andunderground
28、 mines but does not apply to the following:(a) Mining equipment operated beyond the natural visual and audible range of anoperator, e.g. teleoperated equipment.(b) Automatic guided vehicle systems.(c) Automatic conveyor and shuttle systems.(d) Special purpose machines and equipment.(e) Cranes.(f) Sh
29、aft and drift winders.Following any modification to a machine or remote control equipment, the remote controlsystem shall remain in compliance with the requirements of this Standard.1.3 RELATIONSHIP TO REGULATIONS The requirements of this Standard may beread in conjunction with, but do not take prec
30、edence over, regulations of a regulatoryauthority that may apply in a specific area.1.4 INNOVATION Novel materials, designs, methods of assembly, procedures orsimilar which do not comply with a specific requirement of this Standard or are notmentioned in it, but which give equivalent results to thos
31、e specified, are not necessarilyprohibited. Specific approval remains the prerogative of the relevant regulatory authority.1.5 INTERPRETATIONS Questions concerning the meaning, application, or effect, ofany part of this Standard may be referred to Standards Australia/Standards New Zealandfor explana
