摘要
为研究深层灰岩含水层水化学特征,以淮北—朱庄煤矿为例,对12组水样进行常规离子水化学类型判别及多元统计分析。研究结果表明:阳离子质量浓度总体变化特征为Na+>Ca2+>Mg2+,阴离子变化规律为HCO3->SO42->Cl->CO32-;阴、阳离子三角图、相关性分析及主成分分析共同揭示,目前灰岩含水层正进行着硫酸盐矿物溶解、盐岩和碳酸盐岩溶解,以及硅酸盐矿物风化等水-岩相互作用。
In order to discuss the hydro-chemical characteristics of the deep limestone, this paper analyzed 12 samples＂ major ions to master its hydro-chemical type, as well as implemented the multivariate statistics. The re- suits are as follows： The variation characteristics of cations＂ concentration is Na＋〉Ca2＋〉Mg2＋ ,and the anion is HCO3-〉 SO42-〉 Cl-〉 CO32-.Based on the analysis of triangle graph of cation- anion, correlation analysis, principal component analysis, water-rock interaction of the aquifer conclude the dissolution of sulfate mineral, salt rock and carbonate rock, and the weathering of silicate mineral.
