摘要
采用"NPV矿业优化软件",根据L-G法对马依托背矿区最终开采境界进行了优化圈定。采用简化的Bishop法,对露天边坡进行稳定性分析,不仅降低剥采比,而且为该矿区露天开采边坡安全提供技术支持。研究结果可以提高矿山资源回收利用率,并在一定程度上减少露天开采的边坡失稳事故。
In this paper,＂NPV mining optimization software＂is used to optimize and delineate the final openpit mining limit of Mayituobei mining area according to L-G method.Open-pit slope stability is analyzed by using simplified Bishop method.As a result,stripping ratio is decreased,and technical support of slope safety is guaranteed in open-pit mining of this mine.At the same time,it increases the recycling rate for mineral resources and decreases slope instability accident to some extent.
