摘要

Deep-hole presplitting blast technology is an effective method to intensively increase the permeability of coal seam and high-efficiency extract gas. Aimed at the drivage shaft working place of opening No. 13-1 Coal seam influenced by fault in Panyi Coal Mine, this paper comprehensively took advantage of the technology of deep-hole presplitting blast and intensified increasing permeability, the technology of reinforcing coal body using metal skeleton, as well as the technology damming and extracting gas of outside of metal skeleton, diminished the outburst risk only after 18 days, and got the purpose of rapidly diminishing outburst risk. And this provided an effective solution of rapidly diminishing outburst risk and safety opening coal seam for similar conditions.
