Abstract: In order to improve the overall safety of coal mine, combined with antecedent-behavior-consequence(ABC) behavior analysis method, through human factors analysis and classification system, we divide coal mine unsafe factors into four kinds of cause factors, 18 kinds of human factors, and establish human factors analysis and classification system(HFACS) model. Taking Shanxi Luning Coal Mine as an example, we calculate the weight of each factor by analytic hierarchy process(AHP), and obtain the overall safety expression of mine through the obtained mine grade evaluation matrix from grade questionnaire. The analysis results show that human factors in Luning Mine are better, and unsafe factors are safety atmosphere of organization and unsafety psychology of miners. We propose the countermeasures to solve these unsafe factors.
