Abstract:Shangliang coal is a mine of coal and gas outburst, its coal seam is of low permeability. For the gas extraction problem of low permeability of coal seam in Shangliang coal, taking its 32206 first mining face as the test face and with the application of CO2 presplitting blasting antireflection technology, the permeability of coal seam and gas drainage rate are improved, the coal bed gas content and gas pressure are reduced, and the outburst danger of coal seam of working face is eliminated, which is of significant technical effect and provides reference for similar coal mine gas drainage.
