摘要
为了研究复合顶板巷道围岩变形及破坏规律,结合镇城底矿工程实际,应用RFPA分别模拟了一般顶板巷道和复合顶板巷道开挖后围岩的动态变化过程,得出了复合顶板条件下巷道围岩变形和破坏的特征,从而为该矿巷道的支护设计提供科学依据。
To study deformation and failure rule of surrounding rock of laneways with compound roof, combining the real case of Zhenchengdi Mine, dynamic changeable processes of laneways with generic roof and that with compound roof are simulated with RFPA respectively.Then, deformation and failure characteristics of surrounding rock of laneways with compound roof are obtained, which can provide scientific basis for support design of laneways in this mine.
