松软破碎围岩巷道掘进支护技术研究

Research on Support Technology for Excavation of Roadway with Soft Broken Surrounding Rock

以松软破碎围岩巷道掘进支护为对象开展探究。结合具体工程实际,在分析巷道围岩失稳原因的基础上,对掘进巷道围岩支护方案优化开展分析探究,并对优化后方案的应用效果进行了观测分析。结果表明,优化后的方案实现了对围岩的有效控制,能够为掘进作业的安全开展提供保障。

The excavation support of roadway with soft broken surrounding rock was discussed. According to the actual engineer-ing practice, based on the analysis of the reasons for the instability of the surrounding rock of the roadway, this paper analyzed the optimization plan of the surrounding rock support of the roadway, and observed and analyzed the application effect of the optim-ized scheme. The results show that the optimized scheme achieves effective control of the surrounding rock and can provide guarantee for the safe development of the excavation operation.
