掘进巷道断层构造治理技术研究与应用实践

Research and Practice Application on Fault Structure Administer Technology in Driving Roadway

为解决断层影响区域顶板及煤体破碎、支护困难、影响施工效率问题,深入研究断层构造影响区域岩层赋存情况,摸清断层构造影响区域力学特质,根据断层实际赋存情况及安全生产需求,确定采取断层注浆加固、优化断层构造影响区域支护参数。经过治理,工作面通过断层构造影响区域期间,顶板相对完整,煤壁片帮得到改善,工作面安全快速通过。

In order to solve the problems of affecting local roof and coal body fragmentation,support difficulties,and construction efficiency by faults,in-depth research is conducted on the occurrence of rock layers in the area affected by fault structures,and the area mechanical characteristics affected by fault structures are understood.According to the actual occurrence of faults and safety production needs,fault grouting reinforcement and optimization of support parameters in the area affected by fault structures are determined.After treatment,the period of the working face passing through the area affected by fault structures,the roof is relatively complete,and the coal wall caving is improved,ensuring safe and rapid passage of the working face.
