离子型稀土矿常采用原地浸矿法开采,浸矿过程中,矿区坡体材料的强度参数、密度、渗透系数等会逐渐发生变化,对边坡稳定性有较大影响.文中以某离子型稀土矿区边坡为案例,基于强度折减法和有限差分法,考虑浸矿过程中坡体材料强度参数、密度、渗透系数等的变化,研究不同浸液时间和注液强度下的边坡稳定性.计算结果表明,随着浸液时间的逐渐增加,边坡稳定性逐渐降低;相同浸液时间下,注液强度越大,边坡水平位移越大,边坡稳定性越差.
Influence of In-situ Leaching on the Stability of Slopes in Ionic Rare Earth Mines
Ionic rare earth ores are often mined using in-situ leaching method.During the leaching process,the strength parameters,density,permeability coefficient,etc.of the slope material in the mining area will gradually change,which has a significant impact on the stability of the slope.The article takes a slope in an ionic rare earth mining area as a case study,based on the strength reduction method and finite differ-ence method,considering the changes in strength parameters,density,permeability coefficient,etc.of the slope material during the leaching process,and studying the slope stability under different immersion times and injection intensities.The calculation results show that as the im-mersion time gradually increases,the stability of the slope gradually decreases;Under the same immersion time,the greater the injection inten-sity,the greater the horizontal displacement of the slope,and the poorer the stability of the slope.
