摘　　要：针对矿井奥灰含水层在疏降水量数值预测中边界条件和内部结构难以概化问题,以蔚州矿区单侯矿井为例,在综合分析抽(放)水试验、矿区地质剖面以及矿井突水等水文地质资料的基础上,建立区域性自然边界模型,刻画矿区边界条件的水力性质及含水层内部结构的非均质性特征,并在利用地下水位动态观测资料对模型进行识别验证的基础上预测出矿井疏干开采方式下的疏降水量。In view of the problem that it is difficult to generalize boundary conditions and internal structure of Ordovician limestone aquifer in the numerical prediction of mine discharge, taking Danhou Mine of Yuxian Mining Area as an example, we established regional natural boundary model, depicted the hydraulic nature of boundary conditions and heterogeneity of internal structure of Ordovician limestone aquifer based on the analysis of many data, such as pumping test, geological section and water inrush. Finally, on the basis of using underground water level dynamic observation data to identify and verify model, we forecasted water discharge under the way of drainage mining.
