Abstract

Disclosed is a plough mining installation for the underground working of minerals, preferably those occuring in thin seams, which incorporates plough bodies interlinked by rigid rods into a ploughing system reciprocating along the face due to a reciprocatory means consisting of an immovable hydraulic ram and a plurality of movable hydraulic rams. Spaced apart along a frame of the installation, the movable hydraulic rams are linked to each other by articulated joints resting on slides arranged to travel on longitudinal guide means. Thus, the ploughing systems is capable of reciprocating through a distance equalling the length of the aggragate stroke of all the hydraulic rams.
