Assessment of Water Environmental Status in Subsided Water Area of Coal Mine and Its Comprehensive Utilization
摘要
Abstract
In this paper, to accurate assess the water quality in subsided water area of coal mine, the methods of principal component analysis and fuzzy comprehensive assessment are adopted and mended to establish comprehensive evaluation model for water quality of subsided water area. 14 large-scale subsided water areas in Panji mining area of Huainan have been chosen to layout sampling sites and conduct sampling and monitoring for assessing the pollution status of water quality in subsided water area. The assessment results show that variance contribution rate of PCI (first principal component) has been increased significantly after being improved, and enhanced to 98%. When the variance contribu-tion rate of PCI has exceed 85%, the whole indexes of PCI are chosen as evaluation factors of fuzzy comprehensive assessment model to assess water quality, the assessment results show that all of sub-sided water areas have been polluted in various degree. Because the unified evaluation indexes have been chosen to assess water quality, the assessment results of the same type subsided water areas are comparable, and the results can be used as the foundation data for programming and utilizing subsided water resources and constructing "plain reservoir" in Huainan.关键词
