Abstract:
In order to explore the comprehensive evaluation method of environmental pollution control in coal subsidence area, on the basis of the literature review and status analysis, a fuzzy matter-element extension model for comprehensive evaluation of environmental pollution control effect in coal mine subsidence area was constructed by selecting 24 evaluation indexes in four categories, and the application research was carried out by taking the comprehensive evaluation of environmental pollution control effect in Dongtan mining area of Yanzhou mining group company as an example. The evaluation results of criterion layer show that the environmental pollution control effect of the mine is relatively poor, and the development of evaluation results is not balanced; the evaluation results of the target layer show that the effect of environmental pollution control has been improved from moderate pollution (levelⅢ) in 2012 to mild pollution (levelⅡ) in 2020, and the treatment has not reached the expected goal, and the effect may change from rising to declining trend. On this basis, the countermeasures and suggestions are put forward to improve the environmental pollution control effect in coal mine subsidence area.
