| 摘 要： | 本文分析了采煤影响下峰峰矿区自1980年至2017年期间五个不同时期奥灰水的水化学数据，分别利用Pipper三线图、离子相关性分析和多元统计学中的主成分分析等方法分析了奥灰水水化学的演化过程。分析结果表明：高强度的煤矿开采活动已经影响和改变了奥灰水水化学成分，促动其向高离子含量演化。随着煤矿开采年限的延长，奥灰水水化学主控离子也随之改变，原来的HCO3-主控阴离子逐渐被SO42-取代，水化学类型趋于复杂化；水-岩作用由最初的碳酸盐反应为主导演化成后期的硫酸盐反应为主导，并伴生了很明显的离子交换作用。

| Abstract: | In order to further evaluate the impact of coal mining on the ordovician limestone(OL) water environment, this paper studies on the hydro-geochemistry data of OL water in five different periods from 1980 to 2017 in the Fengfeng coal-mining area, analyzes the development the hydro-geochemistry processes by using Pipper trilinear diagram, ions correlation analysis and principal component analysis. The results showed that the high-intensity coal mining activities had affected and changed the hydro-geochemistry characteristic of the water, developed its higher concentrations and more complicated hydrochemistry types. During the coal mining continues, the domination ion of hydrochemistry in OL water also had changed the anion from HCO3- to SO42-.At the same time , the water-rock interaction had changed from carbonate reaction to sulfate reaction, accompanied with obvious ion exchanges. |
