多层孔隙、裂隙—岩溶含水层组的立体充水结构，是华北煤田矿床水文地质概念模型的主要特征。“拟三维”有限元数值模拟模型和其对应的优化管理模型不仅从立体空间的尺度真实地描述了其水文地质概念模型，而且本身也是一项能够为该类型煤田矿井防治水决策系统提供定量科学依据的防治水技术。
The three-dimensional water-filled structure of multi-pore and fissure-karst aquifer is the main feature of conceptual model of hydrogeology in North China Coalfield. The “quasi-three-dimensional” finite element numerical simulation model and its corresponding optimal management model not only describe its conceptual model of hydrogeology truthfully from the scale of three-dimensional space, but also provide a quantitative science for this type of coal mine water control system Based on the prevention and control of water technology.
