摘　　要：露天开采是矿山开采方式中对地下水影响较为严重的一种。本文针对钾长石矿露天开采铁离子对地下水资源影响的科学问题,开展地下水模拟预测。数值模拟预测结果表明,假设污染物铁持续入渗的前提下,将污染物浓度值放大后,在一定的时段和范围内,地下水体中铁的浓度不能满足《地下水质量标准》中Ⅲ类水体的要求,但污染面积及浓度皆较小。Open-pit mining is one of the mining methods that has a serious impact on groundwater.Aiming at the scientific problem of the influence of iron ions on groundwater resources in opencast mining of potash feldspar mine,this paper carries out groundwater simulation and prediction.The prediction results of numerical simulation show that,under the premise of continuous infiltration of pollutant iron,after amplifying the pollutant concentration,the concentration of iron in groundwater can not meet the requirements of class III water body in groundwater quality standard within a certain period of time and range,but the pollution area and concentration are small.
