摘　　要：通过对塌陷区水域的监测,从不同角度对塌陷区水域的水质状况进行了分析评价.结果表明:大通塌陷水域属于轻度污染,潘三矿塌陷水域属于中轻度污染,而谢二矿南大塘污染相对较严重,属于中度污染;从富营养化程度划分,大通塌陷水域是贫营养型,潘三矿塌陷水域是中营养型,而谢二矿南大塘是富营养型.大通矿和谢二矿塌陷水域水质属于Ⅴ类,潘三矿塌陷水域达到Ⅳ类水质标准.The present situation of the water area subsided by coal mining was inspected, and the water quality was analyzed and evaluated from different angle. The results indicate that water area of Datong coalmine is classified as the slight pollution level, that of Pansan coalmine is at slight to medium pollution level, and water of Xie＇ er coalmine is polluted seriously, then it is at moderate pollution level. Divided from trophic degree, water area of Datong coalmine belong to oligotrophic state, and Pansan coalmine is mesotrophic and Xie＇ er coalmine is eutrophic. Water area of Datong coalmine and Xie＇ er eoalmine can reach Ⅴ class standard, and water area of Pansan coalmine can reach Ⅳ class standard.
