To predict the variation of groundwater level of coal mine exploitation and the influence on water source well of the mining area,this paper made numerical simulation analysis of the groudwater flow in the mining area and the surrounding by using Visual MODFLOW software,based on the detailed analysis of area and the hydrogeological conditions of the Zhaozhuang coal mine.It predicted groundwater level,quantity and influence scope at different stage of mining and analyzed the influence of mining on residents drinking water.The identification and testing of the model shows that the proposed model can better reflect the hydrogeological conditions and in accordance with the actual influence of groundwater mining.%为了预测井工煤矿开采后地下水水位变化,及对矿区内居民水源井的影响程度,文章在详细分析赵庄煤矿区域及井田水文地质条件的基础上,运用Visual MODFLOW软件对该煤矿及周边影响范围进行了地下水流数值模拟分析,预测了赵庄煤矿开采后不同阶段地下水水位、水量及影响范围的变化,并分析了煤矿开采对当地居民饮用水源的影响,模型的识别与检验表明,所建模型能够较好地反映水文地质条件,能够与目前实际开采地下水影响相吻合.
