The underground or openpit methods are used for the extraction of mineral resources, each of which is divided into different categories. Coal is one of the mineral resources, which is exploited either by the surface or the underground methods. The longwall mining is one of the methods for the underground coal mining. In this method, which is a mechanized one, some machines such as the ...

GATE END BOX. It is used to supply 550 volt AC to the coal cutting machine working at coal faces. The maximum distance of gate end box from the machine is 100 meter. For putting ON, OFF the switch at 550 volt on the machine itself may produce a spark which is turn may ignite firedamp or coal dust. Hence to avoid this there is pilot switch on the coal cutting machine which works at 30 volts.
