在分析西山煤田某煤矿区域地质及水文地质条件的基础上，将研究区概化为3层结构的地下水含水系统，建立了三维承压非稳定流模型，并采用Visual Modflow 软件求解，对采煤条件下矿区的太灰和奥灰岩溶裂隙水的水位动态进行预测分析。结果表明：煤层开采使两含水层均出现水位下降的现象，采煤2373 d后，太灰含水层的最大水位降深达137 m，并在研究区南部形成疏干区，奥灰含水层的最大水位降深为8.1m。太灰含水层和奥灰含水层地下水水位的下降速度随着煤炭开采时间的延长呈不断减小的趋势。研究成果对矿区水资源保护与防治水措施的制定具有重要意义。

3-layer structure aquifer system was simplified to set up 3-D confined unsteady flow model on the basis of analyzing geolog-ical and hydro-geological condition of a mine area in Xishan coalfield.Applying Visual Modflow software to calculating the model , wa-ter-level dynamic state of Taiyuan limestone and Ordovician limestone Karst fissure water was predicted .Results showed that coal mining made water-level of two aquifers declined.After 2373 days of coal mining , maximum water-level decline of Taiyuan limestone aquifer reached 137m and drainage zone occurred in south of research area , and maximum water-level decline of Ordovician limestone aquifer was 8.1m.Underground water-level decline speed continuously reduced with coal mining time increased.The result had important sig-nificance for water resource protection and water control measurement design.
