摘　　要：运用FLAC数值模拟软件,结合现场地质概况,对大倾角全煤巷锚网索联合支护技术进行了模拟分析,检验了支护参数的合理性,得出了围岩变形特征和围岩应力分布特征,为其他类似条件巷道的锚网索支护参数设计提供了借鉴。Based on the general geological situation, the combined support technology with bolt- mesh- anchor in the full seam roadway of steeply dipping seam was analyzed by FLAC numerical simulation software. The rationality of support parametesr was verified, the deformation feature of surround rock and stress distribution feature of surround rock are found by analysis of numerical simulation, and it will provide some reference for the design of support parameters with blot- mesh - anchor for other similar roadways.
