Description
Technical Field
[0001] The invention relates to the technical field of coal mining, and in particular to a coal mine drilling pressure relief and outburst prevention device based on gas extraction. Background Art
[0002] Gas is a major safety hazard in the coal mining process. The drilling pressure relief and outburst prevention equipment can reduce the gas pressure and stress state in the coal body, reduce the risk of coal and gas outburst, provide safety protection for coal mining, and effectively prevent accidents such as gas explosions. In addition, through drilling pressure relief and gas extraction, the permeability of the coal seam can be improved, making the coal seam easier to mine, reducing the burden on the mine ventilation system, reducing ventilation costs, thereby improving mining efficiency and economic benefits. At the same time, gas is a clean and efficient energy source. Collecting and utilizing gas through gas extraction equipment can not only reduce environmental pollution, but also bring additional economic benefits to the enterprise.
[0003] When drilling to relieve pressure, the position, angle, depth and other parameters of the borehole are selected based on a detailed construction plan and geological conditions. Therefore, the position, angle and depth of each borehole should be precisely controlled.

The deviation angle of existing drilling equipment is 1.5°, and the deviation range is small, which cannot meet the drilling work at all angles and positions of the borehole. At the same time, due to the special nature of the tunnel, its surface is irregular, so there are deviations in the boreholes made according to the original parameters under this plane, which reduces mining efficiency and increases production costs.
