摘要
为对离子型稀土矿原地浸矿边坡稳定性进行预测,首先结合离子型稀土矿原地浸矿边坡特征,分别选取表土层和全风化矿层的重度、黏聚力、内摩擦角以及原地浸矿注液强度等7个因素进行正交实验.其次利用响应面法原理对正交实验结果进行分析,建立离子型稀土矿原地浸矿边坡稳定性分析模型,并将该模型应用与某稀土边坡实例,结果该模型对离子型稀土矿原地浸矿边坡稳定性预测精度高,且符合工程实例,说明了响应面法可应用于离子型稀土矿原地浸矿边坡稳定性分析.
In order to predict the slope stability of the ionic rare earth ore slope in situ leaching mining,combined with the characteristics of ionic rare earth ore in situ leaching slope, the severe, sticky cohesion and internal friction angle and in-situ leaching liquid injection intensity of surface soil layer and weathering layer were selected for orthogonal experiment. Then, by the use of response surface methodology principle, the orthogonal experiment results were analyzed to establish the model of ion rare earth ore in situ leaching mining slope stability analysis, and the model is used for a fact. The results show that the model of ion rare earth ore in situ leaching mining slope stability has high prediction accuracy, and the results suit for the fact, which shows that response surface method can be used for analyzing ion rare earth ore in situ leaching mining slope stability.
