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.
