软岩巷道围岩稳定性控制研究

该文在分析软岩巷道围岩地层结构的基础上,进行了岩石力学参数测试和围岩注浆加固实验;提出了以巷道围岩锚注为核心的复合支护方式,该方式可形成围岩支护体的封闭式结构,有利于提高支护效果。

the paper measures the mechanical parameters of the rock and carries out the grouting reinforcement test of the wall rock based on the analysis of the stratigraphic structure of the surrounding rocks. The author puts forward the composite supporting mode mainly of bolt grouting of the surrounding rocks of the roadway, in the mode a dosed structure of the surrounding rock can be formed as a supporting body which helps to improve the supporting effect.
