摘要
以水质分析、岩石化学组成检测资料为基础,分析了韩城矿区象山矿井奥灰水质的赋存与分布等水文地质背景,重点研究了水化学组分特征。结果表明:对水质类型划分、TDS含量变化贡献最大的为SO42-,Cl-,Na+,Ca2+,Mg2+,其绝对含量随含水层段的埋深而增加。水化学组分垂向上差异,由介质石膏含量及其溶解作用决定。在象山矿井深部奥灰水水动力条件较浅部活跃。
The occurrence and distribution of karst hydrogeological background in Hancheng coal mine are analyzed,based on water quality and rock chemical composition detection.Water chemical characteristics is studied mainly.The results show that SO42-,Cl-,Na＋,Ca2＋,Mg2＋ is largest contribution to water quality classification and TDS and content increases with buried depth.Vertical differences of water chemical composition,decided by the content of gypsum and its dissolution.Deep carst water is more active than shallow.
