Mining TBM (Tunnel Boring Machine)

The invention belongs to the technical field of tunneling equipment, and particularly discloses a mining TBM which comprises a main machine and a rear matching system, the main machine comprises a cutterhead and a shield body, a transfer channel used for transferring an advance drilling machine and gas collecting equipment is arranged in the shield body, the cutterhead comprises a fixed disc and a wobble disc, the wobble disc is hinged to the fixed disc, and the wobble disc is arranged in the shield body. A wobble plate oil cylinder used for driving the wobble plate to swing forwards is arranged between the wobble plate and the shield body, the wobble plate swings forwards to be unfolded so as to form a channel door of the transfer channel, and the cutter head further comprises a locking structure used for limiting the wobble plate to be kept closed. According to the mining TBM, when the mining TBM needs to be retreated for gas treatment, the cutter head can be retreated by a certain distance, the advanced dr
