Operation of advancing and retracting the roof bolter used in coal mines（haoyun）

The editor from Shandong Haoyun Heavy Industry Machinery Co., Ltd. is here to provide the following information for the hydraulic anchor rod drilling truck’s advance and retreat operations in coal mines.

Firstly, Haoyun Heavy Industry must ensure that the floating coal on the bottom plate does not exceed 200mm after the tunneling machine has cut the coal, otherwise it is prohibited to start the drilling truck for support.

Secondly, when the bottom plate tilts, it needs to be leveled to prevent accidents caused by the tilting of the drilling rig. For situations where the slope of the roadway exceeds 12 degrees and the horizontal inclination angle of the floor is greater than 5 degrees, it is strictly prohibited to use drilling trucks for support.

Furthermore, when starting the drilling rig, someone must be responsible for guarding the cables and it is prohibited for only the driver to operate. After the anchor rod drilling vehicle is adjusted, it should stop at a distance of no less than 300mm from the permanent support before conducting online operations.

Finally, after the hydraulic anchor drilling truck of Haoyun Heavy Industry enters the working face, the supporting materials should be kept away from the drilling rig to ensure safety.

These points need to be executed with caution to ensure the safety of coal mining operations.
