Equipment Armoured Face Conveyor (Face Coal Haulage) Once the coal is cut, it has to be removed from the face to the maingate, so some form of coal haulage system is required. In early hand-working days, belt conveyors were used, but these are not amenable to high production rates as the whole conveyor had to be moved sideways to advance the face.
