Tunneling method for coal mine strike type high suction tunnel

The invention provides a tunneling method for a coal mine strike type high suction tunnel, belonging to the technical field of down hole rock tunnel excavation equipment and aiming at providing a tunneling method for a coal mine strike type high suction tunnel; the tunneling method utilizes small-sized TBM (tunnel boring machine) equipment for excavation and is high in security and fast in speed; the technical scheme adopted for solving the technical problem is that the tunneling machine is manipulated to swerve by controlling a walking cylinder at one side of the tunneling machine to elongate and controlling a walking cylinder at the other side to shorten; the tunneling machine swerves and enters the space above a second working plane boring hole and excavates the high suction tunnel till the upper part of a return air large tunnel; the tunneling machine is manipulated to swerve by controlling the walking cylinder at one side of tunneling machine to elongate and controlling the walking cylinder at the other
