Comprehensive Evaluation of Mine Safety Based on Improved Game Theory

Abstract

In order to better evaluate the mine safety, this paper uses the improved comprehensive weighting method based on game theory to comprehensively evaluate the mine safety. Firstly, this paper uses the analytic hierarchy process to subjectively weight the indicators and uses the entropy weight method to objectively weight the indicators, and analyzes the weights of the indicators including personnel, environment, management and equipment. Then, the game theory method is used to coordinate the proportion of the two weights, and the final comprehensive weight is obtained. In the scoring part, the triangular fuzzy number method is used to synthesize the qualitative and quantitative indicators and score them. Finally, the final score is obtained by combining the comprehensive weight and the comprehensive score. In the case analysis, the safety of the three mines is analyzed by this method. By comparing the scores of each other, the level of safety and the shortcomings of each mine can be judged.
