庙沟铁矿露天扩界采场边坡稳定性研究

Study of Slope Stability of Open-pit Extended Stope of Miaogou Iron Ore Mine

通过对露天采场边坡岩体特征分区勘查、露天采场边坡风化破碎带测试分析结果、露天采场边坡岩体质量评价结果和露天采场现状边坡稳定性计算,得出边坡安全系数计算结果,对边坡安全系数计算结果进行分析,并提出边坡防水等建议。

Through survey of rock mass characteristics on slopes of open pit stope by areas and calculation of current slope stability of open-pit stope,and based on testing and analysis results of weathered zone of open pit slopes and evaluation results of rock mass quality of open pit slopes,calculation result of slope safety factor is obtained.Analysis for calculation result of slope safety factor is made and suggestions such as slope waterproofing are put forward.
