摘　　要：介绍剥离废石排土压坡护坡的新方法：与传统的削顶压脚的治理边坡方法相比，前者充分利用剥离废石压住整个最终边坡实现边坡治理。新方法适用于具有内排条件的矿山。运用二维有限元证明了华北某露天与地下联合开采矿山应用这种方法的有效性。The paper has presented an effective pitching method called waste dumping to cover slope, compared to the traditional means named crest cutting to caret toe, the former can make full use of the stripping rock to cover the entire slope. The new method is applicable to mines with in - pit waste disposal condition, and its validity has been proved by the two dimensional finite element analyses for an open pit with underground mining which located in north China.
