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。
Aiming at the difficulty of generalization of the boundary conditions and the internal structure in the prediction of dewatered water volume in Ordovician aquifers, a case study of single Hou mine in Weizhou mining area is carried out in a comprehensive analysis of pumping (releasing) water test, mine geological section and mine water inrush Based on the hydrogeological data and other data, a regional natural boundary model is established to characterize the hydraulic properties of the boundary conditions and the heterogeneity of the internal structure of the aquifer. Based on the verification of the model using the dynamic observation data of groundwater level Predict the mine dredging mining mode of precipitation precipitation.
