针对铜川徐家沟煤矿高应力软岩区域永久性巷道支护后存在变形量大、变形持续时间长、翻修率高等问题，在分析高应力软岩巷道围岩特性的基础上，利用FLAC3D软件进行了3种支护方案的数值模拟，得出穿层斜巷围岩变形和破坏的基本特征，揭示了穿层斜巷非均匀破坏的机理，并提出通过加固底板以控制巷道底鼓的措施，为高应力软岩区域穿层斜巷的支护设计提供了依据。

To counter to the problems of large deformation, long duration of deformation and high repair rate of the roadways after permanent support in the high-stress soft rock area in Tongchuan Xiujiagou Mine, numerical simulation was made on three support schemes with FLAC3D software based on the analysis of the characteristics of its surrounding rock, the basic features of surrounding rock deformation and destruction of the cross-measures inclined roadway were obtained, the mechanism of its heterogeneous destruction was revealed and the measures for strengthening the floor and controlling the floor heave were put forward, all of these provided a theoretical basis for the support design of the cross-measures inclined roadway in high-stress soft rock area.
