摘要
为了分析废弃凹山铁矿矿坑地表水对地下水流场分布的影响,本研究通过监测并分析凹山矿坑周边地下水位动态变化特征,并利用GMS软件中的MODFLOW模块建立地下水数值模型,模拟分析研究区地下水流场的变化特征。结果表明:将凹山矿坑区域等效为高渗透系数的单元体,能够有效地模拟矿坑地表水与地下水的补给过程;凹山矿坑地表水与地下水的水位动态变化基本一致,以矿坑地表水补给地下水为主。研究结果对分析废弃矿坑周边地下水流场演化规律以及评估地下水污染具有重要的理论和现实意义。
In order to analyze the influence of surface water on the distribution of groundwater flow field in the abandoned Aoshan iron mine pit,this study monitored and analyzed the dynamic changes of groundwater level around the Aoshan mine pit,and used the MODFLOW module in GMS software to establish a groundwater numerical model to simulate and analyze the variation characteristics of groundwater flow field in the study area.The results show that the recharge process of surface water and groundwater in the pit can be effectively simulated by equivalent the pit area to a unit with high permeability coefficient.The dynamic changes of surface water and groundwater levels in the pit are basically the same,and the surface water of the pit recharges the groundwater.The research results have important theoretical and practical significance for analyzing the evolution law of groundwater flow field around abandoned mines and evaluating groundwater pollution.
