Abstract: In order to reduce the occurrence of coal mine safety accidents, the system dynamics(SD) method is adopted to construct an SD model of factors affecting the unsafe sentiment of miners from the miner group level, social media network level, and coal mine enterprise governance level. Vensim PLE software was used to simulate the micro-evolution trend of the influencing factors of miners’ unsafe emotions. The results show that the improvement of emotional leadership and organizational emotional carrying capacity can effectively control the unsafe sentiment of miners; coal mine enterprises should timely use the “leader persuasion effect” and “media effect” to disseminate real and effective information to control the increase of unsafe emotional intensity of miners. Therefore, coal mining enterprises should pay attention to the changes of miners’ emotions, actively manage unsafe emotions, and avoid the occurrence of safety accidents.
