The safety production situation for coal mines has been so serious that it was urgent to involve in coal mine risk management in China in recent years. Human induced risk factors were the most important predispositions for accidents in the coal mine systems. Taking one Coal Industry Group Co., Ltd. in Henan province, China as target, the human induced risk factors were comprehensively investigated by the combination of questionnaire survey, interview method and STOP behavior observation method, and then human risk factors used to assess human induced risk status in the Coal Industry Group Co., Ltd. were concluded into five management modules, including 30 concrete human induced risk factors (HIRFs). Further more, the weights of HIRFs were certified by the combination of the weighted average values of expert scored results and frequencies of HIRFs in 210 unsafe behaviors as well as 269 different levels of typical accidents. The results demonstrated that professional quality, basic quality, individual ideology, executive force of safety decision-making and normalization of safety decision-making were the top five important HIRFs in the coal mine systems in China. Reason structure of human induced accidents in the coal mine systems were founded by frequency analysis and logical reasoning, which indicated that professional quality and basic quality accounted directly for the unsafe behaviors while nearly all the HIRFs were observed in the coal mine systems. At the basis of theories discussed above, the relationship between variations of HIRF values and risk levels at the basis of historical data on the official website and data of survey were finally fitted by SIGMPLOT 11.0, and there was a total increase in HIRFs values threshold of (7.44, 18.19) for human induced accidents, that was, accidents below major levels occurred when the HIRF values were lower than 7.44 while the death accidents began to increase when HIRF values were higher than 18.19, which did benefits to prevent and control human induced accidents in the coal mine systems.
