摘　　要：大倾角煤层回采巷道围岩变形与破坏有其独特性,存在非对称变形与巷道围岩受载不均匀性。论文应用FLAC2D对大倾角煤层回采巷道在不同参数条件下的锚杆支护进行了数值分析,得出了不同支护参数下巷道围岩矿压显现规律,为大倾角煤层回采巷道进行锚杆支护设计提供了理论依据。The surrounding rock deformation and failure of the mining gateway in deep inclined seam have its features. There are asymmetric deformation and the load non - homogeneity of the gateway surrounding rock. The paper had a numerical analysis on the bolt support of the deep inclined mining gateway under different parameters with FLAC2D. The strata pressure behave law of the gateway surrounding rock under different support parameters was obtained, which could provide theoretical basis for the bolt support design in the mining gateway in deep inclined seam.
