摘要:
针对魏家地煤矿1070巷道返修工程,分析了复杂应力条件下软岩巷道破坏机理。研究表明,导致1070巷道出现顶板下沉量大、底板严重膨胀、两帮位移大的主要原因是巷道埋深大,构造应力高,采空区矿山压力显现显著。确定锚注锚网联合支护作为1070巷道返修方案。监测结果表明,1070的返修支护方案合理,效果良好。
Abstract:
According to repairing supporting engineering of 1070 Roadway in Wei Jia-di Coal Mine, stability failure mechanism of soft rock roadway engineering under complex stress conditions is analyzed. Research shows that roof subsidence of 1070 Roadway is considerable, expansion of bottom plate is serious, and displacement of two sides is large. The reason that 1070 Roadway has this deformation characteristics is large buried depth, great structural stress, and significant mining pressure in mined-out area. Combined supporting by bolt-grouting and bolt-net is taken as repairing scheme. Monitoring results show that repairing supporting scheme is reasonable, and the good effectiveness is obtained in the practical application.
