摘要： 针对相邻露天矿并行开采时面临的压帮内排与二次剥离问题，分析了不同三角煤回收量引起的境界剥采比的变化趋势，确定了全压帮内排时合理剥采比的判断准则。并以我国黑岱沟和哈尔乌素露天矿并行开采为例，通过分析得出2015年黑岱沟露天矿开采位置应回收三角煤的宽度为209.3m。

Abstract: In view of the problem of the pressure difference between the inner dumping and the repeat stripping in the adjacent open pit, the change trend of the boundary stripping ratio is analyzed. The judgment criterion of reasonable stripping ratio of the total pressure to the inner dumping is determined.Taken the Heidaigou and Haerwusu open-pit mine as an example, through the analysis the Heidaigou’ width of the triangle coal recovery should be 209.3m.
