大变形碎裂岩体巷道锚注加固实践

Practice of anchoring and grouting in large-deformation cataclastic rock tunnels

针对玲珑金矿255m主运巷保护矿柱受民采破坏的具体条件,分析了巷道破坏原因,并简单介绍了锚注加固技术,通过数值模拟和实验室试验进行了锚注参数设计。工程应用实践表明,锚注加固参数设计正确,锚注加固效果明显,为矿山安全生产提供了保障。

As the protecting matin convey tunnels at 255 roof Linglong＇Gold Mine were destroyed, the paper analyzes the reasons for it, and give a brief introduction of the anchoring and grouting technique. The parameters of anchoring and grouting were conducted through numerical simulation and lab test. Practice shows that the parameters were effective, the grouting result was satisfaetory, and laying a foundation for safe mining.
