Abstract: In order to evaluate miners’ emergency ability reasonably, the evaluation model of miners’ emergency ability maturity was established. Firstly, based on the information processing model of miners’ emergency ability, the information processing process and psychological mechanism of miners’ danger information perception, danger information processing, choice, judgment and decision, and operation response were analyzed, and then the evaluation index system of miners’ emergency ability was constructed. Secondly, the maturity level and basic characteristics of miners’ emergency ability evaluation are determined, and the membership function value of miners’ emergency ability maturity is represented by mutation series method. Finally, the model is applied to a coal mine in Shaanxi Province. The results show that the workers of the coal mining team are weak in the aspects of situational awareness, connection ability and decision-making ability, which should be further cultivated and improved. The evaluation result of this model can reflect the real level and weak link of miners’ emergency ability, and can provide management basis for improving miners’ emergency ability.
