Unsafe Behavior

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 was occurred because unsafe behavior induced the dangerous factor in work environment. In order to further acquaint of it, 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 others. As workload increased, goal strengthened, the attention apperceived safe information is weaken and the major change of safe information wasn’t apperceived immediately in work environment, and the accident was happened in conditions of unsafe behavior. Finally, the accident model based on situation cognition was posed and some measures were proposed.

Coal Mining Subsidence

Soma has mine subsidence problems associated with production. Therefore, property and infrastructure damage will be related with coal-mine subsidence in Soma. In this study, depending on the underground coal mine production method, damage of subsidence on energy line was determined in Soma-Turkey coalfield. Subsidence may still occur in these areas. Therefore, determining subsidence is very important. Finite element methods (FEM) and field measurements were used for determining the parameters of mechanisms. The software, Phase2, used for the numerical modeling was developed by Rockscience Inc. The results obtained from modeling have been found to be compatible with previous studies and have been compared with actual field observation.
