| 摘 要： | 通过分析万峰矿地质及水文地质资料，研究万峰矿井太原组灰岩含水层水文地质特征，应用Visual MODFLOW软件，建立太灰含水层地下水数值模型，通过模型计算模拟太灰水流场动态特征，预测当回采工作面太灰水位疏降至含水层底板+160 m时，太灰含水层趋于疏干，工作面顶板太灰水的疏降水量为750 m3/h，为工作面安全回采及矿井排水设施的建立提供依据。

| Abstract: | Through the analysis of geological and hydrogeological data of Wanfeng Mine，by analyzing hydrogeological characteristics of Taiyuan formation limestone aquifer in Wanfeng Mine，numerical simulation model of Taiyuan formation limestone aquifer groundwater was established by using Visual MODFLOW software. Through the model simulation，the dynamic characteristics of Taiyuan formation limestone aquifer groundwater flow field was simulated，and it was predicted that，Taiyuan formation limestone aquifer became unwatered when the water level of Taiyuan formation limestone aquifer went down to +160 m on aquifer floor，and the dewatering quantity of Taiyuan formation limestone aquifer on working face was 750 m3/h. |
