Abstract: 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.
