摘要
通过对锚注支护机理的阐述,研究锚注支护修复巷道的可行性。结合丁集矿典型返修巷道变形与破坏形式特征,设计该返修巷道锚注支护方案,并完成了现场监测分析与评价。实践表明,该技术是解决深井高应力软岩返修巷道支护的有效途径,具有较高的推广应用价值。
This article illuminates the bolting - grouting mechanics and the feasibility of repairing the tunnel. Combines with the deforming and damage way feature of the typical repairing tunnel in Dingji coal mine, the bolting - grouting scheme of repairing tunnel is designed and the site monitoring analysis and estimating were accomplished. The results of the practical test showes that the technique is an effective way to solve the problems of high stress repairing tunnel supporting. It has the higher value in application and dissemination.
