摘　　要：依托于某萤石矿生产单位的供水水文地质调查项目,在矿区及周边154 km^(2)范围内开展了1∶5万初步供水水文地质调查。综合考虑地形地貌、水系分布、地层岩性、构造背景,按照赋存条件将研究区地下水划分为冲洪积松散岩类孔隙地下水、火山岩类风化带裂隙地下水、石英脉及萤石脉构造角砾岩空隙地下水、断裂构造裂隙地下水、碎屑岩类孔隙裂隙地下水共五种地下水赋存模式;结合前期已有开采井水文地质试验成果,确定石英脉及萤石脉构造角砾岩空隙地下水蓄水构造、断裂构造裂隙地下水蓄水构造具有满足矿区1万m^(3)/d供水需求的供水前景。Based on a water supply hydrogeological survey project of a fluorite mine production unit,a 1:50000 preliminary water supply hydrogeological survey was carried out in 154 km^(2) around the mining area.According to the topography,water system distribution,stratigraphic lithology and tectonic background,the groundwater in the study area was divided into five groundwater occurrence modes:alluvial loose rock pore groundwater,volcanic rock weathering zone fissure groundwater,quartz vein and fluorite vein structural breccia pore groundwater,fault structural fissure groundwater,clastic rock pore fissure groundwater.Combined with the hydrogeological test result of the existing mining wells in the early stage,it is determined that the quartz vein and fluorite vein structure breccia pore groundwater storage structure and fault structural fissure groundwater storage structure have the water supply prospect to meet the water supply demand of 10000 m^(3)/d in the mining area.
