摘　　要：露天煤矿剥采比和剥离量估算的准确性直接影响着露天煤矿开采的投资和设计,传统的估算方法在计算过程中计算点间地形的起伏和煤层的起伏变化控制不足,导致计算结果精确度较低。现代计算机模拟技术可以建立矿山地质模型,模拟地形、煤层等的起伏变化。以印度尼西亚BARA煤矿剥采比及剥离量计算为例,通过克吕格差分法较为精确的计算了煤矿的剥采比及剥离量,通过对比评价可知,该方法较大提高了数据精确度和工作效率。The accuracy of estimation of stripping mining ratio and stripping volume in surface mine directly affect the investment and design of the mine, the traditional estimation change control is insufficient in calculating the fluctuation of the terrain and coal seam, which caused the low accuracy of the calculation result. The modern computer simulation technology could set up mine geology model, simulating the fluctuation change of the terrain and coal seam. Stripping mining and stripping volume calculation of BARA Mine in Indonesia was taken as example, the two indexes were calculated precisely based on Krueger difference method, the technology improved the data accuracy and working efficiency by comparison and evaluation.
