FIELD: mining equipment, particularly for coal excavation from coal beds.
SUBSTANCE: executive tool comprises at least one bore bit connected by auger pipe with auger machine head and non-rotating pipe with feeding machine mechanism. Arranged on non-rotation pipe are support skis and hydraulic jack for executive tool operation in vertical plane. Working chambers of hydraulic jacks are hydraulically connected with outlets of electrohydraulic distributors. Pressure inlets of electrohydraulic distributors are connected by flow splitter arranged on non-rotation pipe with pressure source, namely with spraying hydroline. Drainage outlets of electrohydraulic distributors are connected through channels formed in non-rotation pipe body at least with one drainage orifice arranged beyond the boundary of non-rotation pipe and provided with protective case.
EFFECT: increased operational reliability and production.
