Outline
To accurately identify the key factors influencing the mining safety of underground metal mines and clarify the internal interaction logic among the influencing factors, an integrated analysis model for factors affecting mine mining safety based on Grey-DEMATEL-ISM-MICMAC was constructed. Through literature review and case analysis, 17 influencing factors were screened and identified from five dimensions: personnel, equipment, environment, management and technology. The Grey-DEMATEL method was employed to quantitatively analyze the importance of each factor. Combined with the ISM method, a multi-level hierarchical structure model was constructed to reveal the interrelationships among the factors. Finally, the MICMAC method was used to analyze the attribute characteristics of the factors. The research results indicate that the 17 influencing factors can be divided into 6 levels and 3 types. Employee training and education, safety production management system, safety hazard identification and rectification, and rationality of mining technology are the core influencing factors of mine mining safety, possessing characteristics of high driving force and low dependency. The reliability of safety protection devices, daily equipment renewal and maintenance, environmental hazard source control, working environment conditions, key technology application, and technological innovation are direct influencing factors, exhibiting high dependency characteristics. In response, combined with the actual engineering situation, targeted optimization measures are proposed, guided by the modernization and practicability of the management system, centered on the comprehensive improvement of personnel quality, based on the improvement of the working environment, and supported by the upgrading of technical equipment. The research results can provide theoretical basis and decision-making reference for enhancing the level of mine safety management.
