穆利亚希南露天边坡稳定性分析

露天边坡角的大小对矿山边坡稳定及开采成本有着重要影响，合理的边坡角是保证露天采场安全、经济回采的重要因素。本文以卢安夏铜矿穆利亚希南矿区为背景，应用 Geo-Slope 软件在考虑地震影响因素下使用极限平衡法中的 Ordinary 法、Bishop 法、Janbu 法及 Morgenstern-Price 法对穆利亚希南矿区一区和二区不同角度的露天边坡稳定性进行分析，结果表明 ：当一分区的边坡角为 40°，二分区的边坡角为 39°时，边坡最为稳定，能保证工作平台安全生产。研究成果可为卢安夏其它露天矿边坡稳定性分析提供借鉴。

Stability Analysis of Muliashi South Open-pit Slope

The size of open-pit slope angle has an important impact on the mine slope safety and mining cost. Reasonable slope angle is an important factor to ensure the safe and economic mining of open-pit. Based on the Muliashi north mining area of Luanshya Copper Mine, the stability of the open pit slope in Muliashi north zone 1 and zone 2 mining area is analyzed by using the Ordinary method, Bishop method, Janbu method and Morgenstern price method of the limit equilibrium method with the geo slope software considering the earthquake influence factors, The results show that when the slope angle of zone 1 is 40 ° and the slope angle of zone 2 is 39 °, the slope is the most stable and can ensure the safe production of the work bench. The research results can provide reference for the stability analysis of the slope of other open-pit at Luanshya.
