Crawler hydraulic tunnel drilling rig for coal mines is a device that uses an electric motor to drive a hydraulic pump, a hydraulic motor to drive the tracks, and a hydraulic motor to drive the drill bit. It is used to drill water and gas holes in soft rock or coal seams. It consists of a main hydraulic system, tracked running gear, working mechanism, and frame.

The Crawler hydraulic tunnel drilling rig for coal mines is a new generation of tracked drilling equipment for water exploration, gas exploration, fault exploration, roof caving, and water injection. It is mainly used for dense drilling in soft rock or coal seams where anti-outburst measures are required at the working face, but it is also suitable for other applications. This equipment features a compact structure, flexible operation, good mobility, full-face operation, good safety performance, and multi-purpose functionality. In addition to water and gas exploration, it can also drill into complex strata. It is equipped with ordinary reaming drill bits and other drilling tools, allowing for rotary drilling.

This drilling rig has the following advantages:

1. Safe operation, significantly reducing the physical labor intensity of workers. 1. Suitable for construction of horizontal and inclined tunnels with various cross-sections;

2. Compact structure, fully hydraulic control, convenient and flexible operation, crawler-mounted movement, easy relocation, good mobility, saving time and labor;

3. The drilling rig's power head has high torque and long stroke, resulting in high drilling efficiency and significantly improving work efficiency;

4. The hydraulic system is equipped with a rapid propulsion function, saving more than twice the time for loading and unloading drill rods. It also includes components for loading and unloading drill rods, reducing the labor intensity of operators.

5. Utilizing a variable displacement system, the no-load speed is high, and the speed decreases and the torque gradually increases with load changes, making drilling more efficient.
