摘要
邯邢地区是铁矿和煤炭生产基地，区域水文地质条件基本查清。二叠系上统上石盒子组长石石英砂岩及燕山期闪长岩类，为矿泉水赋存的主要含水层。由于受ＳＮ及ＮＮＥ向断层的切割，岩层被分成若干块段。各块段间含水层互不联系，构成独立的含水系统。由Ｆ＿２２和Ｆ＿２３断层构成的白岗块段，形成了独具一格的白岗矿泉水水源地。矿泉水受区域奥陶系下层灰岩水沿断层的顶托补给，单井最大允许开采量达５１．２３ｍ￣３／ｈ。地下水在径流途中对岩石的溶滤作用，使特征组分Ｈ＿２ＳｉＯ＿３和Ｓｒ富集起来，各项指标均符合国标（ＧＢ８５３７－８７）的要求，形成锶－偏硅酸型饮用天然矿泉水。
In Han-Xing district,the arkose of Shihezi Formation of the Upper Series of PermianSystem and the Yanshanian diorite are the main aquifers of mineral water,Faults in NNE andSN directions cut the region into serveral blocks in which the aquifers are unlinked each oth-er,and thus forming some independent water-bearing systems. Baigang block,bounded byF_22 and F_23 faults is a unique mineral water source. The mineral water is alimented by waterfrom the lower part of the regional Ordovician limestone along the top of the faults.Themaximum minable volume of single well is 5l.23 m￣3/h.The solution and filtration of groundwater during circulation through the country rocks lead to the concentration of H_2SiO_3 ,Srand others up to the GB 8537-87 standard for mineral water,Therefore,it belongs to Sr-H_2SiO_3 natural mineral water.
