摘　　要：某离子型稀土矿采用原地浸矿工艺,由于浸矿液和清水的注入,山体长期处于饱和状态,滑坡的风险较大,采用Geo-Studio软件,应用二维极限平衡法对矿区内典型边坡多工况稳定性进行分析,采取留设保安矿柱和抗滑桩等加固措施。结果表明,矿区内大部分边坡在3种工况下都属于稳定边坡,绝大部分不稳定边坡在采取预留保安矿柱的方法下,边坡安全系数提升明显,均大于设计安全系数,属于稳定边坡。8-2和9-1边坡在采取抗滑桩人工加固后,边坡安全系数也能满足稳定性要求。An ion-type rare earth mine adopts in-situ leaching process.Due to the injection of leaching solution and clean water,the mountain is in a saturated state for a long time,and the risk of landslide is high.Geo-Studio software and two-dimensional limit equilibrium method are used to analyze the stability of typical slopes in the mining area under multiple working conditions.Reinforcement measures such as retaining security pillars and anti-slide piles are adopted.The results show that most of the slopes in the mining area belong to stable slopes under three working conditions.Under the method of reserving safety pillars,the safety factor of most unstable slopes is obviously improved,which is greater than the design safety factor and belongs to stable slopes.The safety factor of 8-2 and 9-1 slopes can also meet the stability requirements after artificial reinforcement of anti-slide piles.
