摘　　要：为解决XV1302工作面瓦斯压力大及采掘接继困难等问题,根据工作面现有情况,通过分析工作面煤层赋存状况和瓦斯涌出特征,采取了本煤层定向钻孔+顺层钻孔预抽、边采边抽、顶板倾向高位钻孔抽采上隅角瓦斯及全封闭采空区抽采瓦斯等技术措施。通过以上瓦斯治理措施,瓦斯含量大幅降低,缓解了采掘衔接问题,经济和社会效益显著。In order to solve the problems of high gas pressure and difficult mining succession in the XV1302 working face,according to the current situation of the working face,by analyzing the coal seam occurrence status and gas emission characteristics in the working face,directional drilling+bedding drilling in this coal seam was adopted.Technical measures such as pre-drilling of holes,side-draining,top-drilling borehole drainage of upper corner gas,and gas extraction in fully enclosed goafs.Through the above gas management measures,the gas content has been greatly reduced,alleviating the problem of mining and connection.Significant economic and social benefits.
