Belt conveyors used to transport minerals are to be found all around the world in a large number of surface and underground mining operations. The idea of using the conveyor belt is not new, indeed, the first bell conveyors were introduced at the end of the nineteenth century; the basic principles of operation have not changed.
In a mine with drift or adit access, the conveyor transport can be all the way to surface but in a mine with only shaft access winding or hoisting of coal in the shaft is required. The use of conveyors introduces a requirement for roadways to be mined as straight as possible with changes of direction minimized as far as possible.
