摘要
采煤塌陷水域是淮南潘集矿区一种特殊的地表水体。为了对潘集矿区塌陷水域进行水质评价和提供水资源综合利用的理论基础,选择了潘一矿区典型的两个塌陷水域,采用格网法布设39个采样点对水质进行全面采样监测,分析了水体的重金属元素和部分理化指标并运用数学模糊综合评判法对水质进行了评价。结果表明,封闭性较好的1#水域水质由水体中间向两岸呈递减趋势,中间断面水质为Ⅲ类;与泥河连通的2#水域水质较差,所有监测断面水质均为Ⅳ、Ⅴ类。由于矿业污染源的影响,导致2#水域的重金属元素污染强度高于1#水域。各塌陷水域均已受到不同程度污染,然而丰富的塌陷水资源若合理保护和综合开发利用可带来显著的环境效益和经济效益。
Excavate coal subsided water area is the special component of the surface water in Panji mining area of Huainan city. 39 sampling points in two typical subsided water areas of Panyi coal mining area were chosen to monitor the water quality for providing the theoretical basis on comprehensive utilization of subsided water resource of Pauji mining area. Besides, heavy metal elements and parts of physieochemieal indexes were analyzed and the fuzzy comprehensive evaluation method was used to evaluate the water quality. The results show that the water quality of well closed subsided water area (No. 1# ) presents a decreasing tendency from the center to banks and the water quality in the center profile is grade III . While the water quality of the subsided water area (No. 2 # ) which is linked to Nihe River is relatively poor and water qualities of all monitored profiles are all grade IV or V . Due to the influence of polluting sources from mining industries and power plants, the pollution intensity of heavy metal elements in 2 # subsided water area is more serious than 1 # water area. The subsided water areas have been polluted in different degree. However, obvious environmental and economic benefits will be obtained if the abundant water resource of Panji mining subsided water area is protected properly and utilized comprehensively.
