为了预测三聚盛煤矿9号煤层开采对上覆含水层的影响，通过研究区的水文地质情况，应用 Vi-sual MODFLOW 软件，对计算域进行剖分，确定二类流边界，对本区地下水流进行了数值模拟。结果表明，煤矿开采12．6 a 后，漏斗中心的水位降深约为75 m ，影响面积约为24．3 km2。通过预测9号煤层开采后地下水水位的变化趋势，为煤矿的后续开采工作和环境管理工作提供相应的理论依据。

In order to predict the impact on the overlying aquifer after the coal mining of No .9 coal seam in Sanjusheng Mine ,and through introducing the hydrogeological conditions in Sanjusheng mine district ,the Visual MODFLOW was ap-plied to simulate the groundwater flow in this area .Through the generation of computational domain ,the secondary flow boundary was determined .The results show that after the coal mining for 10 years ,the water level drawdown in funnel center is about 75 m ,and the influence area is about 24 .3 km2 .By predicting the variation trend of the groundwater lev-el after No .9 coal seam mining ,the results will provide the corresponding theoretical basis for subsequent coal mining and environmental management .
