【摘要】 以新疆阿吾孜苏煤矿具体工程为例,利用FLAC3D软件对不同角度、垂距、围岩强度的交叉段巷道围岩变形特征及规律进行分析。探讨不同条件下交叉巷道交叉段的围岩变形情况,运用灰色关联度分析获得各影响因素对空间交叉巷道稳定性的影响程度,为空间交叉巷道施工和巷道交叉段的支护设计提供有效的参考依据。更多还原

【Abstract】 Takes Xinjiang Awuzisu coal mine specific project as an example,studying on stability of surrounding rock in close range roadway.The deformation of surrounding rock of cross roadway in different conditions is discussed.The influence of each influencing factor on the stability of the space tunnel intersection is obtained by using grey relational degree analysis.Providing an effective reference for supporting design of close range space tunnel.更多还原
