摘　　要：对某矿8、9、12#可采煤层瓦斯涌出量进行分源式预测计算,其中预测8#煤层埋深812.8m时瓦斯涌出量达到30.21 m^(3)/min;预测9#煤层埋深666.7 m时瓦斯涌出量达到62.97 m^(3)/min;预测15#煤层埋深710.11 m时瓦斯涌出量达到39.01 m^(3)/min,并设定以区域性局部预防为主的防突处理方案。防突处理中利用15#煤层高抽巷负压抽采8、9#煤层,同时应用浅孔释放、释放孔抽放、左右耳钻场交替抽放等区域性防突技术。A separate source prediction calculation was conducted on the gas emission rate of the 8,9,and 12#coal seams in a certain mine.It was predicted that the gas emission rate would reach 30.21 m^(3)/min when the burial depth of the 8#coal seam was 812.8m.Predict a gas emission rate of 62.97 m^(3)/min at a depth of 666.7 m in coal seam 9#.Predict that the gas emission rate of coal seam 15#will reach 39.01 m^(3)/min when the burial depth is 710.11 m,and set up a regional and local prevention plan for gas outburst prevention.In the anti outburst treatment,the 15#coal seam high extraction roadway negative pressure is used to extract the 8#and 9#coal seams,while regional anti-outburst technologies such as shallow hole release,release hole release,and alternating left and right ear drilling fields are applied.
