| 地浸采铀对地下水的放射性污染是一个倍受关注的环境问题.本文对新疆某地浸采铀矿山井场地下水污染的监测结果进行了分析，建立了地浸采铀井场地下水中污染物迁移的动力学模拟，对污染物在地下水中的迁移规律进行了数值模拟.在地浸生产期间，有少量的放射性污染物U和硫酸向井场外迁移，但污染物迁移速度和迁移距离都比较小，污染物浓度较低，污染物呈不规则的齿形迁移，U和SO2-4的迁移规律与迁移趋势是一致.数值模拟对分析地浸采铀矿山地下水中污染物的迁移规律、预测和控制污染物的迁移提供有效的途径和依据. |

| The radioactive contamination of groundwater from in situ leaching (ISL) of uranium mining is a widespread environmental problem.This paper analyzed the monitor rasults of groundwater contaminations for a in situ leaching uranium mine.A dynamic model of contaminants transport in groundwater in ISL well field was established.The processes and mechanisms of contaminant transport in groungwater were simulated numerically for a ISL well field.A small quantity of U and SO2-4 migrate to outside of well field during ISL production stage.But the migration velocity and distance of contaminations is small,and the concentration is low.Contaminants migrate as anomalistic tooth-shape.The migration trend of U and SO2-4 is consistent.Numerical modeling can provide an effective approach to analyse the transport mechanism,and forecast and controll the migration of contaminants in groundwater in ISL well field. |
