采动影响下煤矿底板岩巷围岩控制技术

Surrounding Rock Control Technology of Coal Mine Floor Rock Roadway under the Influence of Mining

回采面推移中的采动影响对巷道围岩稳定性有着一定的负面影响,如何实现对围岩的有效控制,事关生产安全。以此为出发点,结合具体工程实际,在分析巷道初始支护和矿压监测的基础上,对巷道支护优化开展了探究,并对其应用效果进行了测验。结果表明,优化后的方案实现了对巷道围岩的有效控制,为生产作业的安全开展提供了保障。

The mining influence during the mining face moving has a certain negative impact on the stability of surrounding rock of roadway.How to achieve effective control of surrounding rock is related to production safety.From this point of view,combining with the concrete engineering practice,based on the analysis of initial support and mine pressure monitoring of the roadway,this paper explored the optimization of roadway support and tested its application effect.The results showed that the optimized scheme could effectively control the surrounding rock of the roadway and provide guarantee for the safe development of production operation.
