Crawler-type full hydraulic tunnel drilling rig for coal mine

In view of the actual situation that the pressure relief treatment of roadway pressure relief treatment and gas drainage treatment is difficult and the gas drainage treatment efficiency is low, our company has newly developed and produced mechanical cave-making equipment for coal mines.
The crawler-type full hydraulic tunnel drilling rig for coal mine is a patented product of our company, patent number: CN202010922779.8, CN202010890623.6. Coal mine soft rock hole expansion support, rockburst control and roof cutting pressure relief, as well as gas prevention and hole bottom hole making in high gas soft coal seam.
The equipment adopts the hydraulic mechanical control principle outside the hole, so that the omnidirectional hydraulic crawler drilling rig can provide the hydraulic ejector driving function, and arrange the corresponding control valve group, and use the control valve group to control the hydraulic oil circuit, cooling water and wind. The construction requires a long-distance high thrust output driven by a mechanical core rod-driven drill pipe, so that the mechanical reamer can be actively opened at the target position of the hole creation through the mechanical ejector rod type drill pipe (patent number: CN202021510251.1), and the hole creation is completed. Automatically shut down afterwards. Greatly improved the control level outside the hole in the cavern-making project.

Performance advantage

1. Using hydraulic mechanical control, using static pressure water, the cave can be completed without a high-pressure pump station;
2. It can be used for different geological conditions such as rock formations with f < 6, and has a wide range of applications, which can meet the needs of rock roadway burrowing and pressure relief, and coal seam burrowing construction;
3. The mechanical control outside the hole greatly improves the success rate of the hole-making project;
4. The construction cost is comprehensively reduced, and the construction efficiency is more than doubled.
The crawler-type cave drilling rig products produced by our company are widely used in various regions at home and abroad. The main domestic application areas are: China Coal Group, Longmei Group, Shenmei Group, Fengfeng Coal Industry, Kailuan Coal Industry, Lu'an Coal Industry, Yangmei Group, Shanxi Coal Group, Xishan Coal and Electricity, Fenxi Coal Industry, Datun Coal Industry, Xinji Energy, etc.; the main use areas in foreign countries: Russia, Australia, Southeast Asia and Northern Europe.
