ABSTRACT:
A mining apparatus comprises a planing device which is movable along a longwall to the drift and has a longwall conveyor which extends alongside it and is deflected into the drift for the removal of the cutaway material. A cutter is operable in the transition between the longwall and the drift and includes a rotatable shaft which is rotatable on a conveyor in the transition between the longwall and the drift and includes an outer arm which carries a rotatable cutting wheel which is moved by the swivel arm through the cutting zone at the transition between the longwall and the drift. The swivel arm is pivotable on a bearing shaft which carries a chain wheel which is driven from a chain drive which operates a plane cutter which is movable along the longwall. The chain drive includes a chain wheel which is rotatable with the bearing shaft and is connected by a separate cutter chain drive which extends through the swivel arm to a chain wheel affixed to the shaft of the cutter wheel.
