摘　　要：文章以安徽宣城某煤矿-500m煤层运输巷为研究对象,分析了大倾角多层软弱夹煤岩层中,煤层运输巷道的支护机理。文章结合该矿的具体施工能力,制定出了较为符合实际情况的锚网索联合支护方案,并利用有限元分析技术给出了支护前后巷道变形情况的对比,研究结果对倾角较大、巷道揭露围岩层数较多、软弱、夹煤围岩中锚索网联合支护技术的应用,有较大的参考价值。In this paper, a-500m coal seam transportation laneway, in a coal mine in Xuancheng city, is researched. The reasonable Support mechanism of coal seam transportation laneway in Steep multi-storey weak terrane and coal seam is analyzed. Anchor net cable integration support project is establishmented by the construction ability of this coal mine. By use of finite element analysis techniques, the deformation contrast, before and after the laneway support, is given. The research results have greater referrence value to coal seam transportation laneway in Steep multi-storey weak terrane and coal seam.
