Abstract: In order to quantitatively analyze influencing factors on practice ability of safety inspectors in coal mines, DEMATEL method was used to determine the relationship between their competence factors from a perspective of emergency theory. Then, based on researches relating to safety capabilities and considering duties of safety inspectors, a conceptual model of professional capabilities was proposed. Finally, an index system of influencing factors was constructed, and modified DEMATEL method combined with entropy weight and G-1 methods were applied to determine relationship parameters of each factor. The results show that among 18 influencing factor indicators, knowledge and experience, psychology and training rank top three in order of importance. According to causal analysis, 8 indicators, including education level, knowledge and experience and training, are cause factors while physiology, psychology and safety skills are result factors.

Key words: safety inspector in coal mines, practice ability, emergence theory, decision making trial and evaluation laboratory (DEMATEL), entropy method, G-1 method
