Study On The Occurrence Mechanism And Prevention Countermeasures Of Coal Mine Accidents Due To Human Factor

This paper discusses the concept and classification of the dynamic touch-to-go risk source and static innate risk source in coal mine and analyzes accidents due to human factor based on theory of safety science and three kinds of hazard. The results show that the eruptive causation that the dynamic touch-to-go risk source bring about the static innate risk source in coal mine cause accidents due to human factor through analysis and research the state of production system and hazard structure of coal mine. According to safety behavior science principles, human error is divided into individual operation error and organizational management failures in coal mine. The paper pointed out that the dynamic touch-to-go risk source is a kind of human error and the static innate risk source results from human error or organizational management failures. It is found out that the aftereffect of accidents that result from organizational management failures are even more serious than the aftereffect of accidents that result from general individual operation error by analyzing the coal mine' accidents in past years in Hunan. The article analyzes and discusses in detail the causes of accidents due to human factor in coal mine by applying theories of safety system engineering and establishes accident forming logic model chart of coal mine production system and FTA mode chart of coal mine accidents' causes. It demonstrates that coal mine accidents due to human factor resulted from the invalidation of the first and the second controlling mechanism. The article makes the dynamic grey interrelation analysis of man and accident by applying the grey interrelation analysis to the mine' accidents in past years in Hunan. This paper concluded that the majority of causing accidents or injured colony is the workers who serve fewer than ten year, schooling at primary school and junior middle school' young workers during the past years. According to the number of accidents in past years at the coal mine, the number of accidents is forecasted in the future by applying the grey forecast theory. This paper has set up feasible grey system prediction models. According to the principle of prevention-in-depth , the paper set up coal mine the prevention-in-depth of accidents due to human factor " the four stages" prevention and management mode. We analyze several ways to prevent accidents due to human factor at coal mine through strengthening the criterion of organization, organization communication, the function of organization and the culture atmosphere of organization etc. Finally, This paper discusses and applies the colony dynamics technology tactics that prevents coal mine accidents due to human factor. This contribution will help colliery to raise safety management levels, to prevent human error and check or reduce emergence of accidents due to human factor at coal mine.
