| 摘 要： | 文章从内排露天矿的内排特点和露天矿边坡断面形式入手,通过比较不同边坡角、不同断面形式的端帮边坡稳定性及最下一个台阶的掩埋高度和时间来分析边坡时效性对露天煤矿端帮靠帮开采的影响。安家岭露天矿充分利用排土场边坡的内排时效性及凸形边坡的边坡设计方法,获得端帮煤量26.56万t,提高了经济效益。

| Abstract: | The in-pit dumping features of the surface mine and the cross section form of the surface mine,the comparison between the different slope angles,different cross section type end slope stabilities,as well as the next below bench buried height and time was applied to analyze the slope time effect affected to the end slop mining and the pit slope mining of the surface mine.With the in-pit dumping time effect of the dumping slope in the Anjialing Surface Mine and the slope design method of the convex slope,the ... |
