Huainan Mining Subsidence Water Situation Analysis and Comprehensive Evaluation to Fengtai County, for Example Zhangji Mine Subsidence Area

摘要

In order to study the rational use of mineral waters Zhangji water resources, four typical Zhangji mine subsidence ponds were selected as research sites. By using GPS positioning system, 12 sampling places were determined for sampling of water. The quality of samples was monitored and analyzed. The fuzzy comprehensive evaluation method was used for water quality analysis and evaluation. The results showed that the four cave-in areas within the region are subject to different degrees of pollution and water use is not sufficient.
