A device for extending flexible power supply lines for mining machines which are guided on a conveyor structure and moved back and forth along a longwall by means of a traction element which includes a coal strand and a return strand extending with an enclosed space comprising a housing secured to the conveyor and enclosing a load strand. A return and a cable channel is alongside the load strand channel, with the flexible supply lines being stored at the ends of the longwall towed along by a mining machine through the cable channel. The housing is secured to the conveyor structure and open at one side, and an idle roller is mounted in the housing in the cable channel. The supply lines are supported on the idle rollers. The mining machine is moved by a traction element and the supply lines bear against the traction element at the open side of the cable channel.

Power supply arrangement for pulled mining machines

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.
