FIELD: mining.

SUBSTANCE: mining tunnelling combine comprises a frame equipped with a travelling mechanism, a boom that carries cutting facilities and a traction facility that passes in the longitudinal direction of the combine behind the back end of the frame. Cutting facilities are formed by at least two rotary cutting heads having axes of rotation passing in direction of tunnelling or arranged at the sharp angle to the tunnelling direction. The mining tunnelling combine also comprises a block suitable for towing behind the frame, having a transverse passage for the traction facility and hingedly connected to the frame by means of blocks of hydraulic piston cylinders. The block comprises at least one boring and setting device for anchors and at least one support device fixed on the roof and foot, each at both sides of the traction facility. On the block there is also a control device connected to the drive of the travelling mechanism and/or drives of cutting facilities and with hydraulic control of blocks of hydraulic piston cylinders, so that blocks switch to free-flow or floating position during combine tunnelling.

EFFECT: invention provides for installation of anchors most closely to the face with simultaneous continuation of boring process.
