摘要
通过分析屯兰矿井下瓦斯赋存的实际情况,在南四盘区12403工作面采用本煤层网状抽放钻孔布置,进行瓦斯预抽放,解决开采层瓦斯涌出.经实际应用,抽放效果较好,对治理采掘工作面瓦斯涌出具有推广价值.
By analyzing the actual situation that Tunlan mine has the occurrence of gas, in the Southern fourth panel 12403 the working face using coal seam reticulated boreholes and predrainaging methane resolve gas emission of the working seam. After the application, it has better effect and a promotional value for management of mining coal seam gas emission.
