FIELD: tunneling machines, particularly, tunneling machines for driving horizontal and inclined mine workings. SUBSTANCE: tunneling and stoping machine includes boom-like working member, body in the form of welded frame structure, pumping plant with system of hydraulic units, supporting skids parallel to longitudinal axis of machine, supporting blades secured to front and rear parts of machine body and consisting of movable members for turning in vertical plane by means of turning hydraulic jacks whose one end is attached to supporting blades and the other, to machine body. Reciprocating motion of skid relative to transverse axis of machine body is ensured by hydraulic jack installed between movable members of supporting blade. Supporting blades are made in the form of closed four-link mechanism. EFFECT: higher productivity of tunneling and stoping machine due to improved stability and maneuverability. 2 dwg
