摘要
根据岩性弱结构巷道的层状岩体结构特征,分析了顶、底板弱结构体岩层的破坏类型及特征,以及离层与挠曲型顶、底板和剪切破坏性顶板的稳定性,对岩性弱结构巷道围岩的控制具有一定的参考价值。
According to rock stratum structure character of weak lithology structure roadways, the failure types and characters of weak structure body in roof and floor, and the stability of roof and floor with separation and flexible layer, as well as stability of roof with sheared failure are analyzed in this paper, it has reference value to a certain extent for control of the weak lithology structure roadways.
