摘　　要：地浸采铀浸出液铀质量浓度受多种因素影响,如矿体形态、矿层与含矿含水层厚度之比、浸出剂酸度等。依据采区抽注过程中地下水运动状态,分析不同井型与地下水稀释量的关系、浸出剂被稀释对浸出液铀质量浓度的影响,并通过计算机模拟,提出窄条带状矿体和正方形矿体浸出液受地下水稀释程度的差异,以及对浸出液铀质量浓度的影响。The uranium concentration of pregnant solution obtained from in-situ leaching is influenced by different factors,such as the shape of orebody,the ratio of orebody thickness to uranium-bearing aquifer thickness,concentration of lixiviant and so on.On the basis of principle of groundwater movement in course of pumping and injection,the relation between well patterns and volume of groundwater dilution,and the influence of lixiviant dilution on uranium concentration of pregnant solution are analyzed.In virtue of computer simulation,the discrepancy of pregnant solution dilution caused by groundwater to the shape of narrow strip and square extend orebody,and the influence on uranium concentration of pregnant solution are proposed.
