为了研究某铀矿原地浸出采矿井型及井距选择及优化方法,对原地浸出采矿选择井型及井距的基本原理进行深入分析,论述了选择井型及井距时需要考虑的影响因素。运用Visual Modflow软件对行列式井型与七点型井型及不同井距下的井型进行数值模拟,结合矿山井型选择原则、矿山实际条件和技术经济条件,对水头剖面图、溶质浓度分布图及溶质运移路线图进行分析。结果表明:适合该矿山的合理井型为七点型,该矿山的最优井距为25 m。研究成果可为类似矿山提供参考。
In order to study the selection and optimization methods of in-situ leaching mining well type and well spacing for a uranium mine, the basic principles of on-site leaching mining well and well spacing are analyzed in depth, and the impacts that need to be considered in choosing well type and well spacing are discussed factor. Visual Modflow software is used to simulate the well type of the determinant well, the seven-point well type and the different well spacing. Combined with the mine well type selection principle, the mine actual conditions and the technical and economic conditions, the water head profile, the solute concentration distribution Figure and solute transport roadmap for analysis. The results show that the reasonable well type suitable for the mine is seven-point type, and the optimal well spacing of the mine is 25 m. The research results can provide reference for similar mines.
