摘　　要：煤矿资源开采产生的煤矿山酸性废水污染是全球关注的环境问题,煤矿山酸性废水具有pH值低、铁、锰和硫酸盐含量高、含有重金属等特点,给生态环境造成极大的危害,其处理通常较复杂、昂贵且难度大。本文介绍了煤矿山酸性废水形成机理及危害,综述国内外煤矿山酸性废水防控与治理技术研究发展现状并分析这些技术的优缺点,探讨了煤矿山酸性废水防治技术发展趋势以及面临的挑战和机遇。同时调查贵州省喀斯特地区闭坑煤矿山酸性废水水质特征并探讨其治理策略。Acid mine drainage(AMD)from coal mining continues to be a global concern due to great hazards to the ecological environment.The AMD from coal mining has the characteristics of low pH value,high content of iron,manganese and sulfate,and containing heavy metals.Treatment of such AMD is often complex,costly and challenging.This paper introduces the formation mechanism and harm of AMD from coal mining,summarizes the research status of AMD prevention and treatment at home and abroad,analyzes the advantages and disadvantages of these technologies,discusses the development trend,and explores the associated challenges and opportunities that AMD poses for environmental scientists and researchers.In addition,the characteristics of AMD from closed pits of coal mines in Karst areas of Guizhou Province were investigated and its treatment strategies were discussed.
