摘要
原地溶浸采矿开采工艺越来越广泛运用于离子型稀土开采过程中,但在溶浸液长期渗入及化学作用下,岩体物理化学性质发生改变,使得边坡强度降低,造成边坡失稳。本文以赣南某稀土矿边坡为研究对象,运用室内模拟浸泡试验分析了该矿稀土土样的工程性质,采用数值模拟方法分析了边坡的稳定性,并给出了相关结论,为赣南离子型稀土开采过程中边坡治理工作提供参考依据。
The in-situ leaching mining technology is more and more widely used in the ionic rare earth mining process,but because of long-term infiltration into leaching solution and under the action of chemical,physical and chemical properties of rock mass change,make the decrease of strength of slope,slope instability. This paper,taking a mine of Jiangxi slope as the research object,indoor simulative immersion test is used to analysis engineering properties of the rare earth soil,the numerical simulation method to analyze the stability of the slope,And give the relevant conclusion,provide a reference basis for Ganzhou＇s ionic rare earth mining slope in the process of governance work.
