PLOUGH MINING INSTALLATION 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 articu- lated joints resting on slides arranged to travel on longi- tudinal guide means. Thus, the ploughing system is capable of reciprocating through a distance equalling the length of the aggragate stroke of all the hydraulic rams.
