Abstract： In Xinyuan Coal Mine, aiming at the problems of low efficiency, large engineering quantity and long outburst elimination period in the coal roadway driving and extraction method of No.3 coal seam, the experimental research and application of large liquid water sand fracturing and gas phase fracturing antireflection technology in the ground vertical well were carried out. The gas control was carried out mainly by the large liquid water sand fracturing in the ground vertical well and combined with the gas phase fracturing antireflection technology in the underground. The three-dimensional outburst prevention technology system suitable for the outburst coal seam in the mine was formed, and the outburst danger of the coal seam in the outburst area was eliminated, and the purpose of efficient production was finally realized.
