A hauling and shaving plant for underground mining of a mining face particularly a coal face which is adjacent a rock face disposed at an angle thereto comprises a longwall conveyor section which is adapted to be positioned alongside the coal face and a rock face section extending at an angle to the longwall conveyor section. A plane guide is associated with the conveyor and a plane is movable along the guide. A shaving chain guide is associated with the plane guide in the conveyor. A plane chain is connected to the plane and is movable along the plane guide. The hauling chain has a pulling strand and a return strand and is guided along the longwall conveyor. The shaving chain and the hauling chain are driven by drives which are located adjacent the rockwall section. The conveyor includes at least one deflecting pulley over which the pulling strand is directed and at least one return pulley over which the return strand is directed. The return strand is also guided adjacent the rock face in a return channel. A chain channel is located in the rockwall section and extends at an angle to the conveyor alongside the rock face and the pulling strand is directed along the chain channel. The return strand is directed from the longwall conveyor into the chain channel at the coal face end.
