摘要
保证露天煤矿边坡稳定对人员安全、经济效益、开采进度都具有积极作用。本文在分析胜利东二矿工程勘察资料基础上,采用Geo-Studio数值软件建立工程模型,预测东帮边坡的安全系数及潜在滑移面。同时选用相同分析方法对地下水影响下的安全系数求解,分析地下水位对边坡稳定性的不利影响。研究发现三种分析方法求解结果基本一致,边坡存在滑移危险。
Ensuring the stability of open-pit coal mine slopes has a positive effect on personnel safety, eco-nomic benefits, and mining progress. Based on the analysis of engineering survey data of Shengli East No. 2 Mine, this article uses Geo-Studio numerical software to establish an engineering model to predict the safety factor and potential slip surface of the east side slope. At the same time, the same analysis method is used to solve the safety factor under the influence of groundwater, and the adverse effect of groundwater level on the slope stability is analyzed. The study found that the results of the three analysis methods are basically the same, and there is a danger of slippage on the slope.
