Abstract
in order to solve the of gas problems of adjacent layer 9# coal seam in Sihe Coal Mine No. two shaft, analyzed 9# coal seam gas source using the source analysis method, and developed a detailed design which is adopted the roof km directional drilling arrangement and the coal seam gateway layout borehole layer as the main means, Practice has proved, through two kinds of borehole layout, effectively solved the 9# coal seam gas overrun problem, provided the security for the regional staff safety, at the same time for mine gas drainage under similar conditions to provide reference.关键词
