某地浸矿床抽注液井距研究:Visual-MODFLOW在某地浸矿山井距确定中的应用

对某地浸矿山水文地质条件进行详细分析、整理,分析了影响地浸矿山抽注液井距的主要因素,从理论上计算出适宜矿山抽注液井距的范围,同时给出推荐的井距。运用Visual-Modflow建立三维地下水流数值模型,运用模型模拟抽注液井距,对三种不同井距23m、27m、30m进行了模拟,模型计算结果表明,23m、27m井距从技术上更为合理,能够较大的覆盖矿体范围,减少溶浸死角。运用经济分析对23m、27m井距进行优化,结果表明27m井距综合效益最优,从而确定了矿山抽注液井距采用27m。

The research on interval between pump and affusion well of insite uranium mine

Analyzing the geohydrologic conditions of the insite uranium mine.Research main complications on interval between pump and affusion well.Calculate the interval by theory and commend academic data.The project use Visual-Modflow to construct three-dimension groundwater numerical model.The pump and affusion well had disposal in model.Modelling process of exploitation drew the conclusion of interval between pump and affusion well.The result of model were 23m,27m and 30m.In technically,the better interval were 23m and 27m which overlay the most mine.In financial,the best interval was 27m.In conclusion,the 27m was the greatest interval between pump and affusion well.
