高、突煤层消突及瓦斯综合治理工作的实践

Practice of Gas Outburst Elimination and Gas Comprehensive Management in High Gas and Outburst Seam

根据鸡西矿区荣华立井7#煤层存在的突出和高瓦斯特征,采用了分阶段的瓦斯综合治理方法。通过采用保护层开采、本煤层瓦斯预抽、仰角钻孔、高位水平钻孔、低位钻孔、上部采空区贯通钻孔等综合瓦斯治理方法,成功地实现了突出煤层消突、高瓦斯工作面安全回采,实现了安全高效生产。

According to the characteristics of outburst and high gas in No.7 coal seam in Ronghua Mine of Jixi mine area,the comprehensive gas control method with segments was used.Through the use of protective seam mining,the coal seam gas drainage,elevation drilling,horizontal drilling,high level drilling,low drilling,upper goaf through drilling and other comprehensive gas controlling method,the outburst eiminatiom in the outburst coal seam,and mining safety at the high gas working face,were successfully realized to achieve safety and high efficient production.
