基于Visual Modflow的地下水污染模拟研究

新峰一矿地下水是矿区的主要供水水源,随着采矿活动的加剧,地下水受到一定程度污染。为了预测地下水环境的变化,利用Visual Modflow软件建立了新峰一矿地下水水流模型和污染物运移模型进行模拟。收集整理了大量地下水监测报告和研究报告的数据用于模型的建立,详细的地下水位和水质监测数据用于模型校正。用校正的模型分析预测了未来5 a内太原组上段灰岩含水层地下水中污染物扩散趋势。

Simulation Study on Groundwater Contamination Based on Visual Modflow

Groundwater is one of the major resources of water supply in Xinfeng No.1 Coal Mine.But groundwater had been contaminated to some degree by the aggravation of mining activities.To predict the change of groundwater environment,Visual Modflow software was used to establish underground flow model and pollutants transport models in Xinfeng No.1 Coal Mine.Large amounts of groundwater monitoring reports and some useful data were collected and obtained for building models,detailed monitoring data on groundwater level and water quality were used to calibrate the models.The calibrated models were applied to predict the tendency of pollutants concentration and dispersion within the coming 5 years under different pump rates in aquifer of limestone of upper Taiyuan Formation.
