Combined with coal seam.occurrence and geological condition in Shuangliu Mine, long directional drilling wear layers was adopted to remove the outburst and minimize the drilling working, the technology made the gas content reduce from 13.23 m3/t to 4.8 m3/t,gas perssure from 2.3MPa to 0.38MPa after 6 months drainage mining, achieving the goal of outburst elimination, reducing the drilling works and the cost, improving the utilization of drilling.
