摘　　要：为了进一步掌握酸性矿井水下渗过程中介质迁移规律,采用淋溶方法,对渗透过程中的酸性矿井水中主要物质的变化情况进行分析,结果表明,酸性矿井水在下渗过程中与岩体之间的化学反应较为明显,渗滤液中的钙、镁离子等含量大幅增加,同时,由于氧化还原作用,造成渗滤液中的铁离子出现絮凝沉淀,铁离子含量降低且下移速度较为缓慢。酸性矿井水对环境以及土壤的污染较为严重。In order to further grasp the law of medium migration in the process of acid mine underwater seepage,leaching method is used to analyze the changes of main substances in the process of acid mine water seepage.The results show that the chemical reaction between acid mine water and rock mass is obvious in the process of seepage,and the contents of calcium and magnesium ions in the leachate increase greatly.At the same time,due to redox,flocculation and precipitation of iron ions in leachate occur,and the content of iron ions decreases slowly.Acidic mine water pollutes the environment and soil seriously.
