摘要
对某煤矿企业已掘巷道受力状况进行分析,针对采面布置不合理、生产设计不规范等实际问题,提出了布置设计优化方案,并论述了在高应力特殊条件下,锚杆与锚索对支护材料的具体要求。通过优化支护技术,显著地提高了支护效果,控制了巷道变形的发生。
The coal mine enterprises have been digging roadway stress conditions were analyzed to find the mining face layout is unreasonable, the design and production of non- standard, and expounds the optimization scheme of layout design, and discusses in the high stress under special conditions, anchor bolts and specific requirements of supporting materials. Through the optimization of supporting technology. Improve the supporting effect, control the roadway deformation.
