摘　　要：为全面展示皖北矿区松散层厚度分布和水文地质特征,收集和整理了矿区内各矿井各阶段的海量勘探资料。结合4000余个钻孔勘探成果,对该区松散层厚度、基岩面起伏及含隔水层分布等特征进行了系统的总结和分析。研究结果表明:(1)松散层厚度变化与基岩面起伏变化具有一致性,宿北断裂以北松散层厚度小、基岩面浅;以南松散层厚度大、基岩面深,均被新生界松散层所覆盖,且两区自东向西松散层厚度均增厚。(2)北区东部普遍发育"1含1隔",西部"3含3隔"发育稳定;南区"4含3隔"发育较稳定,仅朱仙庄发育"5含",即"红层"。To reveal the thickness distribution and hydrogeological characteristics of loose layer in Wanbei mining area, China, based on exploration results, this paper analyzes the thickness of loose layer, fluctuation of bedrock surface and the distribution of aquifer/quifuge. The results show that ： 1 ） The thickness variation of loose layer is consistent with fluctuation of bedrock surface. In the northern part of Subei fault, the thickness of loose layer is thin and bedrock surface is low, in contrast, in the southern area of the fault, the thickness of loose layer is thick and bedrock surface is deep. From east to west, both regions have a trend of thickening of the loose layer;2） ＂One aquifer and one aquifuge＂ develops in the eastern part of the north region, ＂three aquifer and three aquifuge＂ is formed in the western part of the north region. A strata of ＂four aquifer and three aquifuge＂ develops in the south area, with a particular hydrochemistry of the ＂fifth aquifer ＂ in Zhuxianzhuang coalmine.
