摘　　要：针对煤矿单一煤层开采采空区瓦斯抽采问题,以宏岩煤矿一工作面为目标工作面,采用现场监测手段对工作面垂直煤壁和沿工作面方向瓦斯气体的涌出及分布规律进行了研究,基于束管监测系统的实地测试,分析了不同裂隙带瓦斯抽采钻孔的抽采状况。通过上述研究得到了瓦斯分布的情况和规律,最终提出了采空区瓦斯抽采的层位优化和封孔方式优化。Aiming at the problem of gas drainage in the goaf of single seam mining in coal mines,taking a working face of Hongyan Coal Mine as the target working face,this paper studied the gas emission and distribution law of the working face vertical to the coal wall and along the working face by using field monitoring method.Based on the field test of beam tube detection system,it analyzed the drainage status of different gas drainage boreholes in fracture zone.Through the research,the gas distribution situation and law were obtained,and the layer optimization and hole sealing method optimization were proposed for gas drainage in goaf.
