Abstract
In order to better evaluate the mine restoration, this paper establishes a comprehensive evaluation model. Firstly, G1 method and coefficient of variation method are used for comprehensive evaluation. The land state, vegetation restoration state, water environment restoration state and mine social benefit are analyzed. Secondly, the subjective and objective weight of mine restoration is used to obtain the comprehensive weight. Then, the triangular fuzzy number method is used to comprehensively consider the qualitative and quantitative indicators and obtain the comprehensive score. Finally, the final score is obtained by combining the composite score and the composite weight. According to the case analysis of the three mines, the situation of mine restoration is assessed based on the final score to provide guidance for the mine restoration project.
