Description

technical field [0001] The invention belongs to the technical field of underground development equipment in coal mines, and in particular relates to a large-section multifunctional hydraulic rock bolt drilling rig suitable for rapid support and water exploration operations of large-section roadways in coal mines. Background technique [0002] In domestic coal mines, artificial pneumatic bolting rigs are mostly used for support operations. The artificial pneumatic bolting rigs are labor-intensive, have many potential safety hazards, and are low in efficiency. Moreover, they are suitable for large-section working faces caused by complex underground geological conditions. It is impossible to implement the bolt support driving, which seriously affects the driving footage. In the patent No. ZL201110207324.9 and the invention name is an omni-directional rotating drill arm device, the omni-directional rotating drill arm is introduced in detail, but this patent cannot be applied to ...

AI Technical Summary

Problems solved by technology

[0002] In domestic coal mines, manual pneumatic bolting rigs are often used for support operations. Artificial pneumatic bolting rigs have high labor intensity, many safety hazards, and low efficiency. Moreover, they are suitable for large-section working faces caused by complex geological conditions underground. It is impossible to carry out bolt support excavation, which seriously affects the excavation footage

In the patent No. ZL201110207324.9, the invention name is a patent for an all-round rotating drilling arm device, which introduces the omni-directional rotating drilling arm in detail, but this patent cannot be applied to the rapid support and water exploration operations of large-section underground roadways
