【摘要】 本文通过资料收集、抽水试验、水化学分析和室内资料整理等方法,研究了李粮店煤矿地质、水文地质特征,查明了区域地下水的补给、径流和排泄规律。研究认为,区域地下水的主要补给来源为大气降水,其次为岩溶裂隙水;区域地下水由北西向南东径流为主,主要径流带为断裂破碎带;岩溶裂隙水主要以泉的形式排泄,新生界孔隙水以农灌抽水和蒸发排泄为主。煤层底板为太原组上段灰岩岩溶裂隙承压含水层和寒武—奥陶系灰岩岩溶裂隙承压含水层,岩溶裂隙发育,含、富水性极不均一,水文地质条件相对比较复杂。威胁煤矿安全生产的含水层是太原组灰岩岩溶裂隙承压含水层,该含水层为二1煤层底板直接充水含水层。在综合分析了李粮店煤矿地质、水文地质特征的基础上,研究了矿井充水水源、充水因素、充水通道等;利用水文地质比拟法和稳定流解析法预测了矿井涌水量,即正常涌水量为1400m3/h,最大涌水量为2000m3/h;制定了合理的防治水措施,为以后矿井的正常生产和水害防治提供了科学依据。更多还原

【Abstract】 In this paper, the characteristics of regional groundwater recharge, runoff and discharge have been researched through data collection, pumping tests, water chemistry analysis and data analysis. The main recharge of regional groundwater is precipitation, followed by the karst crevice water; Regional groundwater flow from the northwest to southeast. The main runoff zone is fracture zone. Karst crevice water is mainly discharged in form of spring. Mesozoic and Cenozoic porous water is mainly discharged in agricultural irrigation and evaporation. Coal floor is composed of Taiyuan coal for the upper limestone karst fractured confined aquifer and the Cambrian-Ordovician limestone karst-fractured confined aquifer. Karst fissure is developed and water-bearing are heterogeneous. Hydrogeological conditions are relatively more complicated. Threat to mine safety and production of aquifer is a limestone karst fractured Taiyuan confined aquifer, the aquifer for the two coal floor directly to a water-filling aquifer.Based on the comprehensive analysis of the Liliangdian coal geology and hydrogeological conditions, the water-filling sources and factors and channels have been researched. The mine water is prevented by hydrogeology analogue method and steady flow analysis, the normal water yield 1400m3/h, the largest water yield 2000m3/h. The reasonable prevented measures are formulated, which provide scientific basis for the mine production and flood prevention in the future.更多还原
