HEALTH DIAGNOSIS AND DAMAGE EVALUATION OF ECOLOGICAL ENVIRONMENT OF COAL MINING AREA IN NORTHERN SHAANXI, CHINA

World Mining Congress
The coal mining area in Northern Shaanxi, China, has been taken as the study area, and the damage mechanism of the ecological environment is discussed on the basis of analyzing the characteristics of natural eco-environment and resource development in this area. Mining subsidence is taken as an example, and by using the Gray Correlation Analysis method, the key impact factors have been selected. An assessment model with fuzzy comprehensive evaluation has been constructed, and 12 coal mines have been quantitatively assessed. This paper also constructs an ecosystem health assessment method and index system in the coal mine area on the basis of ecosystem health theory, and assesses the ecosystem health status in the Shenfu coal mining area from 2000–2006. The research results are expected to help the eco-environment protection process in the designated coal mining area.
