Practice of Gas Drainage Technology in High Pressure Seam and Outburst Seam by Pressure - Relief of Ground

摘要

In this paper, through the Xinji a mine surface drilling borehole pressure relief gas for practical investigation and study, analysis of the layout of the ground drilling, the influence scope of ground drilling drainage is investigated, and analyzes the drainage effect and the economic benefit brought by the ground drilling. Practice has proved: ground drilling of the mining area of influence, drainage effect is good, the economic benefit is better than the bottom plate roadway extraction and so on.
