The Accident Process Research of Gas Explosion Based on Situation Cognition
Accident is undesired to anyone. But the research shows that the main cause of accident is unsafe behavior. The interaction mechanism of accident system was analyzed in the process of gas explosion through typical accidents and the conclusion was that the accident occurred because unsafe behavior induced the dangerous factor in work environment. In order to understand it further, the situation cognition of workers in the coal mine production process was analyzed with the research of aviation. The cognition of safe information in work process was affected by workload, goal, work habituation and so on. As workload increased, goal strengthened, the attention to safe information is weaken and the major change of safe information wasnt apprehend immediately in work environment, and the accident happened in conditions of unsafe behavior. Finally, the accident model based on situation cognition was posed and some measures were proposed.
