Abstract: In order to solve the problem of high coal seam outburst danger, soft coal seam, poor permeability and difficulty in extraction in Xin’an Coal Field, a high - pressure water - jet technology for rapid eliminating outbust of cross - cut coal was proposed. By using high-pressure water-jet slotting technique, the high-efficiency and rapid gas drainage is realized in this area, and the application shows that the average gas extraction concentration is increased by 3 times, the average single-hole gas extraction volume increased by more than 5 times; the use of the technology can reduce the gas drainage borehole 82%, uncovering coal time reduced by 73%, saving production costs, ease the replace contradiction of mine pumping, mining.
