Tunnel tunneling system

A tunnel tunneling system, comprising:

• a bolter miner comprising a rack, a cutting device, a drilling device and a control device, wherein the cutting device is arranged on the rack and is swingable in an up-down direction, and the cutting device has a lowest swing angle and a highest swing angle;
• the drilling device is arranged on the rack, the drilling device comprises a drilling rig and a sensor, the drilling rig is configured to drill at least one of a tunnel floor and 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;
• in a process of drilling the tunnel floor by a first thickness through the drilling rig, the control device is configured to reduce the lowest swing angle in response to that the monitoring data signal is greater than a first threshold;
• and in a process of drilling the tunnel roof by a second thickness through the drilling rig, the control device is configured to reduce the highest swing angle in response to that the monitoring data signal is greater than a second threshold,
• wherein the first threshold is a numerical parameter corresponding to a propulsion force when breaking through an interface between a coal seam and a rock stratum below the coal seam, and the second threshold is a numerical parameter corresponding to a propulsion force when breaking through an interface between the coal seam and a rock stratum above the coal seam;
• wherein the drilling device includes a first lifting assembly connected with the rack, the drilling rig is arranged on the first lifting assembly and configured to install an anchor rod, the drilling rig is rotatably connected with the first lifting assembly, the drilling rig is swingable in a height direction and a length direction of the rack to adjust an installation orientation of the anchor rod, and the first lifting assembly is configured to lift the drilling rig to allow the drilling rig to drill the tunnel floor and the tunnel roof;
• a bolter-integrated transportation machine arranged behind the bolter miner and configured to transfer coal rock cut and conveyed by the bolter miner;
• a transfer machine and a self-moving tail, wherein one end of the transfer machine is connected with the bolter-integrated transportation machine and is configured to move synchronously with the bolter-integrated transportation machine, the transfer machine is arranged behind the bolter-integrated transportation machine, the transfer machine is configured to transfer the coal rock conveyed by the bolter-integrated transportation machine, the other end of the transfer machine is lapped with the self-moving tail, and the self-moving tail is configured to transfer the coal rock conveyed by the transfer machine and to move backwards for retreat;
• and
• a belt conveyor arranged behind the self-moving tail, and configured to transfer the coal rock conveyed by the self-moving tail.
