North China coalfield consists of three main aquifer groups: porous-medium, karst-fractured, karst aquifer water filling groups. In the plane view, every aquifer has its respective irregular spatial distribution, complex boundary position, and boundary conditions. The main storage space of the karst aquifer is dissolution-enlarged cracks. The water movement meets the nature of percolation theory. There is a wide range of hydraulic connections between the multi-layered aquifers, including by fracture, collapse column, and preferential flow channel formed in Quaternary and other formations. Water filling source is one of the main conditions for controlling water inrush in coal strata. To reveal the common problem of Permo-Carboniferous coal seam floor karst aquifer water inrush under the control of water-filled mine hydrogeological conditions, the karst water system and geological structure model of coal strata in North China’s major coal mining area are divided into five different modes: “monoclinic Shun set type”, “monoclinic retrograde”, “parallel”, “synclinal basin”, and “fault block and others”. Such a division is based on the superimposed relationships between geological structure of coal strata and flow pattern of water filling resource. Based on this, the characteristics of various structural patterns are investigated. Coal forming age, water filling source, and water filling mode are major factors to analyze water-filled hydrogeological conditions in North China coalfields. They not only can be used for helping mineral exploration and mining layout, but also can lay a foundation to establish hydrogeological conceptual models.
