Equipment Maingate Conveyor amp Boot End. Because the face moves continuously along the maingate, at a steady rate if operating correctly, the required maingate belt length is continuously changing. To allow for this and to avoid too frequent stoppages to shorten the belt, it is normal for special arrangements to be made at both ends of the belt.

When it comes to mining coal, there are two processes by which coal can be removed from the ground surface mining, or underground mining. In Australia, the majority of coal mining is done via the opencast method, although often the method of choice is dependent on certain characteristics of the coal deposit 1.. The opencast, also referred to as the openpit method, is the ideal technique when
