摘　　要：分别讨论了三种赋存状态的矿床采用陡工作帮开采的适用性,指出提高工作帮坡角可以降低生产剥采比,推迟剥离洪峰期的到来;以长滩露天煤矿为例,分析了陡工作帮开采对缓倾斜赋存露天矿的生产剥采比的影响;最后,指出了采用陡工作帮开采时所应注意的问题。The paper discusses the applicability of the deposits of three kinds of occurrence status by mining of steep wall,and points out that it can reduce the production stripping ratio,and delay the arrival of the peak period detachment by increasing the angle of working slope.For example of Changtan Surface Coal Mine,analyzed in detail of the influences on the production stripping ratio of surface mine of gently inclined deposit by the mining of steep wall.Finally,it points out some problems that should be paid attention to when by mining of steep wall.
