摘要 司家营铁矿东边坡为复杂条件下的露天矿边坡,其倾向、倾角与地层基本一致,产状对边坡稳定性不利,水文地质条件属中等复杂,且受爆破震动等多种因素的影响,但前期开采并没有对边坡进行过有效的支护处理,边坡暴露一定的时间后,在降水及爆破震动的影响下,出现多处滑坡和潜在的滑坡征兆。结合该矿东边帮局部滑坡现象,分析了产生滑坡的主要原因,制定了应急处理方案,探讨了永久性边坡治理措施。 The east side-slope of Sijiaying iron mine is an open-pit mine with complex conditions.Its eastern slope is basically consistent with the dip direction and angle of the strata,and its occurrence harms the slope stability.The slope has a medium complex hydrogeological condition,and is affected by various factors,such as blasting vibration.The stratum and bedrock composition are complex,and slopes are not effectively supported at the early stage.After slopes exposed for a certain period of time,landslide and potential landslide sign appeared due to the raining and blasting vibration.Combining with the local landslide phenomenon at east slope,the main reason for landslides is analyzed,the emergency treatment scheme is given,and the programs of permanent slope governance are proposed.
