Vertical shaft heading machine applied to composite stratum

A vertical shaft heading machine applied to a composite stratum comprises a cutter head, a deslagging module, a supporting module, a gripper shoe module and a driving module, the gripper shoe module moves in a three-layer gripper shoe combined mode to enable the whole machine to step, a driving device is responsible for driving the cutter head to rotate and push, and the cutter head excavates the bottom of a well. The upper slag discharging module discharges waste slag generated by well bottom excavation to the ground, and the supporting module is provided with related supporting equipment according to the actual geological condition to temporarily or permanently support the stratum. The gripper shoe module can gradually move downwards along with the tunneling action of the cutter head, and stable movement and accurate guiding are guaranteed. Cutter arrangement of the cutterhead is suitable for the composite stratum, the cutterhead is of a detachable structure, damage to the well wall during well outgoing can
