Abstract:
Based on study of the influence of the coalfield fires on the nature-socioeconomic system, the design strategy of the index system for comprehensively assessing the environmental impact of coal fires is brought forward, and the general index system is established which may be divided into 5 grades and 32 indexes. The fires in Wuda coalfield of Inner Mongolia is taken as an example to show the application of comprehensive assessment of environmental impact of coalfield fires. According to the coal-fire characters of Wuda coalfield, 23 indexes for the environmental assessment is selected. Finally, the comprehensive assessment formula is set up in terms of analytic hierarchy method and complex index method. The assessment results indicate that the environmental impact of coal fires in Wuda coalfield is in the rather serious level, which is consistent with that of qualitative analysis.
