浅谈露天金属矿山边坡稳定性的影响及分析

Discussion on the influence and analysis of slope stability in open-pit metal mines

随着我国经济的快速发展,边坡治理设计越来越受到社会的重视,边坡稳定性分析和治理设计研究具有重要现实意义。塞吉罗拉金矿滑坡区地形总体呈南高北低的斜坡地形,从初步勘察来看,边坡有滑塌的趋势,因此亟需对边坡进行稳定性分析。本文对露天金属矿山边坡稳定性的影响及分析进行研究,总结目前常用的岩质边坡稳定性分析方法,包括简单平面滑动稳定分析方法、复杂平面滑动稳定分析方法、三维楔形体稳定分析方法。采用理正边坡稳定性分析软件计算露天金属矿山边坡稳定性。研究结果表明:楔体安全系数都大于1.2,达到边坡稳定要求。

With the rapid development of China's economy,slope treatment design is increasingly valued by society,and slope stability analysis and treatment design research have important practical significance.The overall terrain of the Sejirola gold mine landslide area is a sloping terrain with high terrain in the south and low terrain in the north.Based on preliminary surveys,there is a trend of slope collapse,so it is urgent to conduct stability analysis on the slope.This article studies the influence and analysis of slope stability in open-pit metal mines,summarizes the commonly used rock slope stability analysis methods,including simple plane sliding stability analysis method,complex plane sliding stability analysis method,and threedimensional wedge stability analysis method.Calculate the stability of open-pit metal mine slopes using the Lizheng slope stability analysis software.The research results indicate that the safety factors of the wedges are all greater than 1.2,meeting the requirements for slope stability.
