Study on evaluation of coal mine hidden danger investigation and management capability based on combination weight-gray VIKOR

In order to evaluate the hidden dangers investigation and management capability of coal mine enterprises, from two aspects of personnel and management, 13 main influencing indicators were selected, the G1 and CRITIC methods were used to calculate the subjective and objective weights of each evaluation index, and then the combination weight of the indexes was obtained according to the combination weight method. The evaluation model of hidden danger investigation and management capability based on VIKOR-gray correlation analysis was constructed. The model was applied to Zhaogu No.2 Coal Mine to comprehensively evaluate the hidden danger investigation and management capability from 2016 to 2021. The application results show that the hidden danger investigation and management ability of the coal mine has increased year by year in recent years. Compared with other methods, this evaluation method has a higher identification for the evaluation values, and the evaluation results are more accurate. It provides certain experience for the evaluation of hidden dangers investigation and management ability of coal mine enterprises.
