Shandong Province Jining City Hengwang Industrial and Mining Machinery Co

Hydraulic tunnel drilling rig for coal mines
Scope of application
This drilling rig is mainly used for underground coal mine drilling for gas extraction (discharge holes, grouting fire extinguishing holes, coal seam water injection holes, anti-outburst pressure relief holes, geological exploration holes and other engineering holes. It is suitable for various coal seams and rock formations with rock solidity coefficients. The drilling rig can drill holes arbitrarily within the azimuth and inclination ranges specified in the basic parameter table.
It has two drilling frame forms: column frame and seat frame, which can be drilled according to the Different drilling rigs are selected for the height and use of tunnels in coal mines. The drilling rig is equipped with a high-pressure water generator and a high-pressure sealed drill pipe to cut seams in coal seams with low air permeability, thus improving the gas drainage efficiency and greatly shortening the time. Drainage time. The drilling rig adopts a hydraulic transmission mechanism, which has the characteristics of large drilling capacity, fast speed, simple operation, stable and reliable work, convenient movement and installation.
