摘　　要：在分析矿区及邻矿水文地质资料的基础上,结合所施工的8个水文地质钻孔的单孔抽水和群孔抽水试验,对矿区含(隔)水层的水文地质条件以及井田边界的进行了研究,认为当矿井开采1煤组时,顶板砂岩水和底板岩溶水为其直接充水含水层,砂岩水以静储量为主,它不会对矿井开采1煤组造成大的危害;底板奥灰岩溶水与太灰水之间联系较紧密,前者补给后者,是矿井突水是防治水研究的重点。得出了本矿1煤组的水文地质条件是岩溶裂隙水以底板突水的形式向矿床充水为主,水文地质复杂程度为中等类型的结论,从而为矿井水害的防治与矿井设计提供了依据。Based on the mine area and neighboring coalmine hydrogeological data analysis, combined with single and group hole pumping tests in 8 drilled hydrogeological boreholes carried out studies on mine area aquifer （aquifuge） hydrogeological condition and minefield boundary. The studies have considered that when coal seam group I is mined the roof sandstone water and floor karst water are the direct water filling aquifers, sandstone water is mainly static reserve will not cause large hazard in coal mining; while the floor Ordovician limestone karst water and Taiyuan Formation limestone water has rather close relations, the later can be recharged by the former, thus they are the focal point in water bursting control studies. Finally came to the conclusion that hydrogeological condition of the coal seam group I is mainly karst fissure water filling in the form of floor water bursting; hydrogeological complexity belongs to the medium category, thus the base of coalmine water disaster control and mine design.
