Abstract: In order to prevent generation of unsafe emotions of miners and improve reliability of human factors, it was particularly important to systematically analyze importance and hierarchical relationship between factors forming unsafe emotions of miners. Based on literature and interview research, 12 miners' unsafe emotions formation factors were determined through Delphi method. Thought decision making trial and evaluation laboratory method,12 miners' unsafe emotions formation factors were gathered into four factors sets, respectively strong cause factor set, weak cause factor set, strong result factor set and weak result factor set. A multi-level hierarchical structure model of miners' unsafe emotions formation factors was constructed through further adopted ISM method. The results show that formation of miners' unsafe emotions is the result of a combination of direct factors, middle factors and deep-seated factors. Insufficient job competence, poor safety attitudes and behaviors of managers, restricted career development, poor interpersonal communication, inadequate safety culture atmosphere, and unsatisfactory welfare benefits are the key factors affecting formation of unsafe emotions of miners, should be given priority attention.
