Abstract

A hydraulic-mechanically operating mine working machine includes a multi-part sword engaging a mine longwall conveyor from below. The machine is pulled by a traction rig disposed on the stowing side of the longwall conveyor, which is supplied from the drift with the liquid media needed for cutting and for control purposes via drag lines accommodated in a special duct on the stowing side. The connection between the drag lines arriving on the stowing side and the working machine at the adit end is established by way of a hose hookup block connected with the tractor hookup block, the tractor hookup block and the sword of the working machine engaging the longwall conveyor from below.
