摘　　要：本文以四川省某新建露天矿山为例,选取某一典型危险设计剖面,采用赤平投影分析法、简单平面滑动分析、楔形体破坏分析和极限平衡法进行综合评价,以期为类似新建矿山高陡边坡设计提供参考。结果显示:岩层结构面切割对该边坡影响较大,坡顶部分中风化泥岩由于受矿区界线限制,无法越界开采,将其清除,有可能发生楔形体破坏,该区开采方案需进一步调整;该典型剖面坡顶局部稳定性不满足规范要求,为确保矿山安全生产,终了边坡结构参数需进一步调整。Taking a newly-built open-pit mine in Sichuan Province as an example,a typical hazard design profile is selected and comprehensively evaluated by stereographic projection analysis,simple plane sliding analysis,wedge failure analysis and limit equilibrium method.in order to provide reference for the design of high and steep slope of similar newly-built mines.The results show that the cutting of the rock structural plane has a great influence on the slope,and the weathered mudstone at the top of the slope can not be mined beyond the boundary due to the limitation of the mining area boundary,so the wedge failure may occur and the mining scheme in this area needs to be further adjusted;the local stability of the slope top of the typical section does not meet the requirements of the specification,and the structural parameters of the final slope need to be further adjusted in order to ensure the safety of mine production.
