FIELD: mining.
SUBSTANCE: machine comprises a bearing frame, a drilling head within a hydromotor, a cylindrical reducer and a pressing cartridge; hydraulic cylinders of head and drilling tool feed along guides, a fixed pressing cartridge and a device of frame rotation in the vertical plane. The machine design comprises pipe oil lines - movable and fixed, which produce telescopic connections between each other, and movable hydraulic blocks, which are connected by traction rods with the body of the cylindrical reducer, and with oil line sleeves with the hydromotor and the pressing cartridge of the head.
EFFECT: higher efficiency of underground well drilling due to higher compactness of machine placement in a mine and increased duration of operation of its oil-driven equipment.
