| 中文摘要: |
| 本文利用地下水数值模拟软件GMS，研究矿石淋滤水对地下水污染的影响。模拟在非正常状况下，矿石经雨水淋滤后，淋滤液中的污染物直接穿透包气带进入地下水运移的情景。经预测，泄漏的污染物铁经过运移后出现短暂超标现象，超标范围未出研究区范围，没有对下游敏感点造成影响。随着时间的推移，污染物在地下水的对流、弥散作用下，污染晕中心浓度逐渐降低，污染晕范围逐渐扩大，直至低于限值。研究成果可为该区的地下水保护措施提供依据。 |
| 英文摘要: |
| The influence of ore leaching water on groundwater pollution was studied by using groundwater numerical simulation software GMS. Under abnormal conditions， after the ore is leached by rain， the pollutants in the leachate directly penetrate the aeration zone and enter the groundwater. It is predicted that the leakage of the pollutant iron after migration is a temporary phenomenon of exceeding the standard， the scope of exceeding the standard is not out of the scope of the plant， and there is no impact on the downstream sensitive points. With the passage of time， under the action of convection and dispersion of pollutants in groundwater， the concentration of pollution halo center gradually decreases， and the scope of pollution halo gradually expands until it is lower than the limit value. This work can provide the reference for groundwater protection in this area. |
