Abstract

A tunneling system includes a bolter miner, a bolter-integrated transportation machine, a transfer machine, a self-moving tail and a belt conveyor. The bolter miner includes a rack, a cutting device, and a bolt support device. The bolt support device includes a lifting assembly, a work platform, a first drilling frame assembly and a stabilizing assembly. The lifting assembly is arranged between the rack and the work platform. The first drilling frame assembly and the stabilizing assembly are arranged on the work platform. The bolter-integrated transportation machine is arranged behind the bolter miner and configured to transfer coal rock cut and conveyed by the bolter miner. One end of the transfer machine is connected with the bolter-integrated transportation machine, and the other end of the transfer machine is lapped with the self-moving tail. The belt conveyor is arranged behind the self-moving tail.
