摘要： A bolter miner includes a rack, a cutting device and a bolt support device. The cutting device is configured for a cutting operation and is arranged on the rack to swing up and down. The bolt support device includes a lifting assembly, a work platform, a first drilling frame assembly and a stabilization assembly. The lifting assembly is arranged between the rack and the work platform and is configured to lift the work platform. The first drilling frame assembly and the stabilization assembly are arranged on the work platform. The first drilling frame assembly has a bolt support position and an avoidance position. The work platform can extend and retract to switch the bolt support position and the avoidance position of the first drilling frame assembly. The stabilization assembly can be supported between the cutting device and a tunnel roof, so as to enhance the stability of the first drilling frame assembly during a bolt support operation.

摘要： A tunnel 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, a drilling device and a control device. The cutting device is arranged on the rack and is swingable in an up-down direction, and has a lowest swing angle and a highest swing angle. The drilling device is arranged on the rack, and includes a drilling rig and a sensor. The drilling rig is configured to drill a tunnel floor and/or a tunnel roof, and the sensor is configured to monitor a set parameter of the drilling rig and generate a monitoring data signal when the drilling rig is drilling. The control device is configured to receive and analyze the monitoring data signal.
