With the construction and development of large-scale mines, long-distance, large capacity, high-speed belt conveyor for mining has been widely used. At present, belt conveyor has become the main means of ore transportation in underground coal mining, gold mining, iron mining, copper mining and other mineral mining production lines.

Another underground conveyor belt that was also used in connection with open-pit mining operations was installed at the New Idria mine. This is probably one of the earliest installations in an underground metal mine. It was employed principally to convey waste from the hanging wall of the ore deposit to a waste dump.

Conveyors at the same time would draw a heavy current which might very well disrupt the whole supply system. Therefore, in order to safeguard the conveyors and at the same time prevent a heavy current, a system of sequence switching is introduced. This is explained in the block diagram as in Fig. 8.6.

Longwall mining is an automated form of underground coal mining characterized by high recovery and extraction rates, feasible only in relatively flat-lying, thick, and uniform coal beds. A high-powered cutting machine (the shearer) is passed across the exposed face of coal, shearing away broken coal, which is continuously hauled away by a floor ...
