摘　　要：选择了淮南矿区不同塌陷年龄的煤矿塌陷塘,通过测试水的理化环境状况指标,得出的结果是:矿区塌陷塘都受到了不同程度的污染,水体的pH值较为稳定,水呈中性,水中溶解氧丰富,电导率、氯化物、总硬度随塌陷时间的增加而增长。并对水质理化特性与季节变化和主要理化指标等进行了讨论和评价,为塌陷塘的开发利用提供了一定的理论基础。Physicochemical environment condition indexes of the water were measured for the mine subsidence pools with different subsidence time. The measured results showed that the subsidence pools in the mining area were all subjected to different pollution, pH value in water body was steady, dissolved oxygen was rich, and the conductivity, chloride and the total hardness increase with the increase of subsidence time. There were horizontal and seasonal changes of the physicochemical characteristics of different subsidence pool, but the changes did not occur markedly. The water quality changes in different seasons and major physicochemical factors were discussed and assessed. This study provides a theoretical basis for the development of subside pool.
