摘要
研究矿井水形成过程 ,对于防治采矿活动引起水环境污染具有重要意义 .以淄博煤矿区矿井水为例 ,分析其形成过程并利用化学平衡热力学法对其进行模拟 .结果表明 ,矿井水的形成分为产酸过程与中和过程 ,矿井水的化学性状是由两过程相对作用程度确定 ;该矿区矿井水的硫酸根源于黄铁矿氧化 ,钙、镁离子不是来自通常认为的方解石与白云石 ,而是方解石和绿泥石 .
Drainage in Zibo coal mining district as a case,its origin was analyzied and simulated by chemical thermodynamic simulation.The results showed that the origin was made up by acid and neutral two processes,and the chemical characteristics of the mine drainage depended upon the relationships between two processes.In the studied mine drainage,SO\-4 2- came from FeS\-2,Ca 2+ and Mg 2+ came from Calcite and Chlorite.
