| 摘 要： | 本论文分析了曙光煤矿2101回采工作面瓦斯超限的原因，针对本煤层瓦斯含量较大的实际情况，探索性采用水平迎面斜交平行钻孔抽放；针对瓦斯涌出所占比例较大的采空区，在相邻的2102运输顺槽施工顶板走向高位钻孔抽放，取得了良好的治理效果，达到了安全生产的目的。

| Abstract: | The paper had an analysis on the causes of the gas content over the limit occurred in No.2101 coal mining face of Shuguang Mine.According to the actual conditions of the high gas content in the mining seam,a horizontal face to face oblique cross parallel borehole was applied to the gas drainage in discovery.According to the high gas emission percentage in the goaf,in the construction of the neighbour transportation gateway in No.2102 coal mining face,the high level borehole drilling along the roof strike wa... |
