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, Yikuang Science and Technology has newly developed and produced mechanical hole making equipment for coal mines. The mechanical hole-making equipment for coal mine is our company's patented product, with patent numbers of CN 202010922779.8 and CN 202010890623.6. The equipment adopts the control principle of hydraulic mechanical ejector rod, and is widely used in hole-making and hole-making and pressure-relief of rock strata in coal mine roadway, hole-making and support of soft rock in coal mine, rock burst control and top-cutting and pressure-relief, and hole-making at the bottom of gas prevention and control holes in soft coal seams with high gas. This equipment
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, Yikuang Science and Technology has newly developed and produced mechanical hole making equipment for coal mines.
The mechanical hole-making equipment for coal mine is our company's patented product, with patent numbers of CN 202010922779.8 and CN 202010890623.6. The equipment adopts the control principle of hydraulic mechanical ejector rod, and is widely used in hole-making and hole-making and pressure-relief of rock strata in coal mine roadway, hole-making and support of soft rock in coal mine, rock burst control and top-cutting and pressure-relief, and hole-making at the bottom of gas prevention and control holes in soft coal seams with high gas.
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: CN 202021510251.1) actively open at the target position of cavity creation, and actively close after cavity creation is completed. The control level outside the hole of the hole-making project is greatly improved.
The main advantages of this equipment are:
1, the use of hydraulic mechanical control, the use of static pressure water, without high-pressure pumping station to complete the hole;
2. It can be used for different geological conditions such as rock strata with f<12, and can be used in a wide range, which can meet the needs of rock roadway cavity pressure relief and coal seam cavity construction;
3. The mechanical control outside the hole of the hole greatly improves the success rate of the hole-making project;
4, the construction cost is reduced comprehensively, and the construction efficiency is more than doubled.
