摘要
张集煤矿1115(3)工作面运输顺槽过含水断层破碎带,发生突水冒顶,出现“岩石流”现象;为了安全穿过冒落区,需对冒落区进行有效可行的加固处理,根据冒落区的实际情况确定架U棚、直接做开切眼、注浆加固三种治理方案;通过三种治理方案分析比较及架U棚方案的实践情况,从安全性、可行性、经济性三方面考虑,最后确定采用注浆技术治理方案,通过运用预注浆技术加固,使冒落区形成一个完整的整体,为安全提供了保障,同时也为1115(3)面相邻阶段工作面通过相邻断层破碎带提供了切实有效的防治措施。
During the transporting of Zhangji coal mine fault, “the rock stream of water” was appeared. In order to pass through （ 3 ） passing through the containing water the dropping district safely, it requires to a feasible plan to consolidate the district effectively according to the actual situation. There have three kind of means, but using the thick liquid to consolidate is the best through the points of safety, practice and economy. This paper points out the advantages of this method which provides the effective measure for 115 （3） faces and its adjacent ones.
