Crawler type full hydraulic tunnel drilling rig for coal mine
In view of the actual situation that the pressure relief control of roadway pressure relief control, gas drainage control and other projects are difficult and the gas drainage control efficiency is low, our company has newly developed and produced mechanical hole making equipment for coal mines.
Coal mine crawler full hydraulic tunnel drilling rig is my company's invention patent products, patent number:CN202010922779.8,CN202010890623.6The equipment adopts the principle of hydraulic mechanical top rod control, which is widely used in coal mine roadway rock expansion hole pressure relief, coal mine soft rock expansion hole support,Impact ground pressure management and cutting pressure relief, andhigh gas softCavitation at the bottom of hole for gas prevention and control in coal seamEngineering.
The equipment adopts the principle of hydraulic mechanical control outside the hole, so that the omni-directional hydraulic crawler drilling rig can provide the hydraulic ejector rod driving function, and the corresponding control valve group is arranged. The control valve group is used to control the hydraulic oil circuit, cooling water and wind. According to different construction needs, the mechanical core rod drive drill rod is matched for long-distance high thrust output driven by thrust, so that the mechanical reamer can pass through the mechanical ejector rod (patent number:CN202021510251.11) Actively open at the target position of hole making and close after hole making. The control level outside the hole of the hole-making project is greatly improved.
The main advantages of this equipment are:
14. Adopt hydraulic mechanical control, use static pressure water, and complete cavity creation without high pressure pump station;
2, can be used to targetf<6The use of rock formations and other different geological conditions, the use of a wide range of, can meet the rock roadway hole pressure relief, coal seam hole construction needs;
3The mechanical control outside the hole of the hole greatly improves the success rate of the hole-making project;
4The construction cost is reduced comprehensively, and the construction efficiency is more than doubled.
