煤矿软岩巷道过断层中注浆加固技术的实践

The Practice of Grouting Reinforcement Technique in Soft Rock Roadway Passing Through Fault in Coal Mine

以柳林煤矿为研究对象,对-340 m大巷过SF-12断层进行了注浆加固技术应用研究,解决软岩煤巷安全过断层组破碎带的难题。实践应用效果表明:该注浆加固技术配合适合的支护形式可保障施工安全和一次支护成功,可降低支护成本,提高经济效益。

Taking Liulin Coal Mine as the research object, the grouting reinforcement technology of - 340 m roadway passing through SF-12 fault is studied to solve the diffcult problem of soft rock coal roadway passing through the fracture zone of fault group safely. Practical application results show that the grouting reinforcement technology combined with suitable supporting forms can ensure construction safety and successful primary support, reduce support costs and improve economic benefts.
