A large-scale mining raise-boring machine mainly solves the problems that a large-diameter raise-boring machine has low capacity for hole-guiding and hole-reaming operations, and is characterized in that four main oil cylinders (1) are uniformly distributed on two sides of a drilling frame (3); the main oil cylinders (1) are fixed in the oil cylinder hole position (18) of a reduction box (16) of a unit head (2) through snap rings (4),thrust nuts (5) and lock nuts (6); cylinder rods of the main oil cylinders (1) are rigidly connected with a machine substructure (11) through main oil cylinder flanges (7); the unit head (2) and the reduction box are arranged between four main oil cylinders (1); and four double-speed variable displacement motors (15) are uniformly distributed at the upper part of the unit head (2). The raise-boring machine has higher lifting force and driving torque, and is capable of drilling inclined wells and vertical wells of 60 to 90 DEG through regulation.
