    摘要： An arrangement for controlling the guidance of a mineral winning plough movable along one side of a conveyor. Control members in the form of leaf springs are disposed between the other side of the conveyor and a roof support assembly. The leaf springs are slidably received in a tubular housing suspended from the props of the assembly by means of independently operable hydraulic piston and cylinder units. The units are connected in an articulated manner to the housing to permit the springs to assume various angular control positions.
