长管注浆在煤矿巷道穿越含水断层破碎带中的研究与应用

The research and application of long-tube grouting in dislocation fracture zone of aquifer of mine roadway

利用瞬变电磁方法、断层突水模拟方法等对皖北煤电集团公司刘桥一矿构造特征、煤层特征及水文地质特征等进行了综合分析,在此基础上,提出利用长管注浆技术穿越刘桥断层含水断层破碎带,并取得了很好的效果,实现了对矿井周围边角煤炭资源的开发,延长了矿井服务年限,预防了涌突水等。

structure characteristics, coal seam characteristics and hydro-geological characteristics are comprehensively analysized by Using transient electromagnetic methods, dislocation simulation methods and so on in Wanbei company Liuqiao first mine, based on that, the use of long-tube grouting technique traversing Liuqiao dislocation fracture zone in aquifer is lodged and good resuhs is achieved, the development of coal resources around the corner of mine, the extension of mine life and prevention on water inrush are achieved.
