| Abstract: | For the problem of single coal seam, poor venting quality and low efficiency of gas extraction on Guqiao coal mine, hyfrofracture permeability improvement technology was put forward, and then the hyfrofracture devices operation rules and drilling technology were analyzed. The field test in 1351(3) working face of Guqiao coal mine shows that: the technology to improve gas drainage effect. |
