摘　　要：以瑞丰煤矿以往地质勘查资料为基础,结合现场调查,对瑞丰煤矿水文地质条件进行综合分析,查明充水水源及途径,得出瑞丰煤矿属岩溶裂隙充水矿床,区内地下水主要靠大气降水补给,充水通道主要以岩溶裂隙为主,其次为采空区巷道、岩石裂隙。并采用比拟法对矿区涌水量进行预测,结合充水因素分析以及顶、底板含水层突水计算,得出煤层开采主要受煤系上覆夜郎组玉龙山段和长兴组地层岩溶裂隙水影响,为煤层开采的主要威胁。此次研究成果为瑞丰煤矿下一步开采及防治水工作提供了可靠的水文地质依据。Based on the previous geological exploration data of Ruifeng Mine,combined with the field investigation,the hydrogeological conditions of Ruifeng Mine were comprehensively analyzed,and the water filling source and way were identified.It was concluded that Ruifeng Mine belonged to karst fissure water filling deposit.The groundwater in the area was mainly recharged by atmospheric precipitation,and the water filling channel was mainly karst fissure,followed by goaf roadway and rock fissure.The comparison method was used to predict the water inflow in the mining area.Combined with the analysis of water filling factors and the calculation of water outburst from the roof and floor aquifers,it was concluded that coal seam mining was mainly affected by the karst fissure water in the Yulongshan section of the Yelang Formation and the Changxing Formation,which was the main threat to coal seam mining.The research results provided reliable hydrogeological bases for the next mining and water prevention and control work in Ruifeng Mine.
