根据地下采矿塌陷露天坑的水文地质特征和地下水现况调查及实验资料，在充分考虑塌陷坑地质条件的基础上，选用不同的地下水运动模式，对尾矿库在不同时期渗入地下水的水量进行了预测，并采用试验、类比、综合分析的方法，阐明了渗漏水对地下水的影响范围和程度，认为塌陷坑尾矿库渗漏水不会对该区域地下水造成污染。 According to the investigation and experimental data of the hydrogeological characteristics and groundwater conditions of underground mining subsidence open pit, taking into account the geological conditions of subsidence pits, different groundwater movement modes were selected and the amount of groundwater infiltrated into the tailings pits in different periods was studied Prediction and experimental, analogy and comprehensive analysis methods to elucidate the scope and extent of seepage water’s impact on groundwater. It is concluded that seepage water from the tailing pond will not pollute the groundwater in this area.
