摘　　要：为研究内排土场的存在对露天矿端帮的影响,在理论上分析了端帮边坡的时效性和内排压帮的原理;利用FLAC3D软件建立模型进行分析计算,研究了内排土场存在与否时端帮上点的移动距离和稳定系数的变化情况,并结合伊敏露天矿进行了效益评估。结果表明:采用内排及时跟进可减少端帮的暴露时间,提高端帮的稳定系数,并能创造可观的经济效益。In order to research the influence of internal dumping on stability of end-slope in open-pits, the theory of end-slope timeliness and internal dumping with burying slope were analyzed. The displacement of the point in end-slope was studied, and the variation of safety factor with the model which was built by FLAC3D. Profit evaluation was made combining with Yimin open-pit. The results showed that ： It reduced the exposure time and increased the safety factor of end-slope with the internal dumping following up, and also it can create respectable economic benefit.
