Aiming at the characteristics of large coal seam firmness coefficient, large gas emission, poor dialysis coefficient and outburst risk in the mining face of outburst coal seam in Dashucun Mine, in order to ensure the complete elimination of outburst risk in the working face and effectively control the gas in the working face, according to the characteristics of outburst coal seam under complex geological conditions and combined with the actual gas control technology, a set of through layer drilling pre drainage + hydraulic punching, "three layers and two key points" goaf gas drainage, medium and high pressure short wall water injection and bedding gas drainage was put forward. This comprehensive gas treatment technology of ensured the effective treatment of gas in the coal face of outburst coal seam, and provided technical reference for the mine.
