Where is the best tunnel drilling rig? The first choice is Jining Hengwang Tunnel Drilling Rig, which has good quality and low price and cannot be found anywhere else!
1. Scope of application of hydraulic tunnel drilling rigs
Hydraulic tunnel drilling rigs for coal mines are mainly used for drilling gas pumping (discharge) holes, grouting fire extinguishing holes, coal seam water injection holes, anti-outburst pressure relief holes, Geological exploration holes and other engineering holes. 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.
Hydraulic tunnel drilling rig for coal mines has two drilling frame types: column frame and seat frame. Different drilling frames can be selected according to the height and use of the tunnel underground in the coal mine. When the drilling rig is equipped with a high-pressure water generator and a high-pressure sealed drill pipe, it can cut coal seams with low gas permeability, thus improving the gas drainage efficiency and greatly shortening the drainage time.
2. Features of Hydraulic Tunnel Drilling Rig
This drilling rig adopts a hydraulic transmission mechanism and has the characteristics of large drilling capacity, fast speed, simple operation, stable and reliable operation, and convenient mobile installation.
