Modification Resreach Of Human Error In Coal Mine Based On Human Reliability Analysis

The massive statistical data indicated that the main reason of coal mine accidents were human errors.Therefore,it is an urgent affair of safety production work to research how to control and reduce human errors in coal mine. Based on the principium analysis of coal mine human errors, this paper puts forward the coal mine personal accident-causing analysis frame of thrice fortification,and uses Cognitive Reliability and Error Analysis Method(CREAM)which is one of the human reliability analysis methods to analyse quantificationally and retrospect analysis root cause of human errors in coal mine personal accidents,then constructs the rectification model of coal mine human errors and puts forward accident fortification countermeasures.Firstly, the paper has discussed the concept and the sort of human errors and oranization errors,points out the base reason of human errors and oranization factors'infection by integrating the"S→O→R"cycle model,and then constructs the principium model of coal mine human errors which is consist of oranization,work team and personal.Secondly, based on the analysis of personal accident-causing, the paper analyses the coal mine personal accident-causing principium,and confirms the coal mine personal accident-causing analysis frame of thrice fortification which is consist of oranization,work team and personal by integrating the forming process and constitute factors of coal mine personal accidents.Thirdly,after the compared of some Human Reliability Analysis(HRA)methods,the paper demonstrates the feasibility of CREAM being used in the coal mine domain. Based on the root cause retrospectibve analysis theoretics of CREAM,it systematically constructs a cause table and a"cause-effect"retrospectibve table to coal mine domain,and the cause genus table is composed of 5 big genus and 24 small genus. According to the expert indicator weights survey of Common Performance Condition(CPC),it is confirmed the effect influence indexρ,and measures quantificationally the human error events in coal mine personal accidents with CREAM'prediction analysis method.Finally, based on the root cause of coal mine personal accidents by retrospectibve analysis of CREAM, and integrated the coal mine personal accident-causing principium, the paper constructs the rectification model of coal mine human errors in the step of"confirming human errors - analyzing function– intervening - surveilling and estimating", and then puts forward the optimize advices of accident fortification countermeasures.
