摘　　要：通过分析峰峰矿区某煤矿矿井地质特征、水文地质特征及充水因素,认为该矿目前开采煤层的直接充水含水层为山西组砂岩含水层、野青灰岩含水层、山青灰岩含水层和伏青灰岩含水层;主要充水通道为导水裂隙、断裂构造、封闭不良钻孔、陷落柱;对矿井安全生产影响较大的充水因素为大气降水、地表水、老空水和含水层水。建议矿井未来开采时,采用以“钻探、物探相结合”的手段查清水文地质条件,对老空水要提前进行探放水,对采区可能存在的底板隐伏导(含)水构造,进行探查治理。Based on the analysis of geological characteristics,hydrogeological characteristics and water-filling factors of a coal mine in Fengfeng mining area.It is considered that the water-filling aquifers are sandstone aquifer of Shanxi Formation,wild bluish limestone aquifer,mountain bluish limestone aquifer and bluish limestone aquifer.The main water-filling channels are water-conducting fissure,fracture structure,poorly sealed borehole and collapse column.The water-filling factors that have great influence on mine safety production are atmospheric precipitation,surface water,goaf water and aquifer water.It is suggested that the method of“combining drilling and geophysical exploration”should be used to investigate the hydrogeological conditions in the future mining of the mine,the goaf water should be explored and released in advance,and the hidden water-conducting(containing)structure of floor in the mining area should be explored and treated.
