通过对山西某煤矿102工作面复用尾巷的围岩结构变形破坏特征以及围岩应力环境实测与分析,提出以中空注浆锚杆、中空注浆锚索为核心的巷道全断面锚注补强加固支护方案,现场应用效果良好,满足尾巷二次复用要求。
Through the deformation and failure characteristics of the surrounding rock structure and the stress environment measurement and analysis of the surrounding rock of the reuse face of 102 coalface in a coal mine in Shanxi Province, it is proposed that the hollow section grouting anchor bolt and the hollow grouting anchor cable should be the core of the whole section. Strong reinforcement support program, field application of good results to meet the requirements of the second phase of the tail lane.
