Abstract:The safety evaluation index system for ecological safety of the coal mining area was established according to the current condition and problems of the ecological safety in the coal mining area and by taking pressure-status-response ( P-S-R) model as the framework and selecting twenty-seven measuring indices. First, the subjective weight and objective weight were respectively determined by using group decision-making AHP and factor analysis method, then the comprehensive weight assembled by both the subjective weight and objective weight was taken as the weight of each hierarchy factor of the model, finally the improved fuzzy comprehensive evaluation method was used to fulfill the evaluation work of the model. A coal mine in Zhengzhou area was first selected as a demonstrative research object, then the field investigation, questionnaire survey and interviews were carried out in this mine, and finally the ecological safety evaluation of the mine was conducted by using PSR model and the improved fuzzy comprehensive evaluation method, it was concluded that the ecological safety level of the mine was"v3" ( general level ) . The research result can provide reference for the government departments and the mining area administrators to improve the ecological safety of the mining areas.
