摘要

应用地下水模拟软件,对地浸采铀井场的水动力渗流场和溶质弥散迁移场进行了量化分析研究。将渗流场分为若干特征区域,定义了粒子渗流域平垂面特征参数、地下水对地浸流场稀释率、注孔流量贡献值等特征参数,同时根据各抽孔的稀释量变化对地浸流场进行了周期划分。在地层均质性、抽注流量、井距、过滤器安放位置及过滤器长度等不同因素影响下,建立内蒙古某地浸井场的水动力及溶质弥散迁移模型,并以这些特征参数为指标对井场进行了量化比较。
        By application of groundwater modeling software,quantitative analysis of in-situ leaching uranium flow field for seepage-dispersion field is carried out.Seepage field is divided into several feature region.Horizontal-vertical characteristic parameters of seepage field,dilution rate of flow field and rate of injection contribution are defined.According to dilution rate change,flow filed is divided into several periods.Based on the stratum homogeneousness,drawing and injecting flow rate,well spacing,filter installation site as well as its length etc.influence factors,the modeling of hydrodynamic force and solution seepage-dispersion field at one in-situ leaching uranium field in the Inner Mongolia is established.Therefore,quantitative comparison is conducted by those parameters at the flow field.
