摘要
针对阜新矿区新邱南部矸石山对地下水污染实际情况,分析了矸石山渗滤液在含水层中运移的规律,建立了渗滤液在地下水系统中运移的耦合动力学仿真模型,利用该模型对渗滤液在地下水中迁移行为进行仿真分析,预测了污染物浓度的分布范围及随时空变化趋势。并与于家沟地区实际检测点数据进行对比,结果表明:渗滤液浓度拟合误差小于6%,从而验证了模型的可靠性和实用性,为地下水资源开发过程中污染控制与治理措施提供依据和理论指导。
The waste rock hill in Xinqiu in Fuxin coal miming area is studied for the pollution of groundwater. The mechanism of waste rock hill leachate in the aquifer has been analyzed. A coupled numerical model is developed for simulating the leachate transport in groundwater system. Solutions to the model are accomplished by Splitting Operator Method, which predict the temporal and spatial distribution features and distribution range of contaminant concentration. The pollution of groundwater of Yujiagou problem is used to provide a quantitative verification and validation of the model. The model simulations are compared to measured data, which are reasonably agreed with model simulation .The result indicates that the average error of leachate concentration is less than 6%. The simulation model provides scientific evidence and methodology for pollutions control and prevention in groundwater resource exploitation.
