摘要
为有效治理前和矿回采面瓦斯异常涌出现象,从地质及采掘技术两方面对其异常涌出原因进行深入分析,并在此基础上针对性地提出"煤壁封堵+瓦斯抽采"的综合型防治措施,瓦斯监测结果表明综合防治措施取得良好效果,有效降低了异常区域瓦斯浓度,为井下作业安全提供了有力保障。
For effective governing the phenomenon of unusual gas emission at working faces in Qianhe Coal Mine, this paper made a deep analysis of abnormal cause from the aspects of geological and mining technology, put forward comprehensive prevention and control measures- ＂coal wall block ＋ gas extraction＂ on the basis. The gas monitoring results showed that the comprehensive prevention measures achieve good results, and effectively reduce the abnormal gas concentration area, which provided a powerful guarantee for underground operation safety.
