深部大变形巷道围岩稳定性控制分析

Analysis of Surrounding Rock Stability Control in Deep Roadway with Large Deformation

结合具体工程实际,在分析原支护方案应用不足的基础上,提出相应的围岩稳定性控制措施和支护设计优化方案,并借助数值模拟手段对原方案和优化方案进行对比分析,结果表明所提出优化支护方案实现了对围岩变形的有效控制,提升了巷道围岩稳定性,为生产的持续、安全开展提供了有力保障。

Combining with the actual engineering practice, based on the analysis of deficiency in the application of the original support scheme, this paper proposed the corresponding stability control measures of surrounding rock and optimization scheme of support design, and compared and analyzed the original scheme and the optimization scheme by means of numerical simulation.The results showed that the proposed optimal support scheme achieved effective control of surrounding rock deformation, improved the stability of roadway surrounding rock and provided a strong guarantee for the continuous and safe development of production.
