Theoretical research on hazards and accident prevention

By applying modern safety science viewpoints and accident-causing theory, and based on case studies, the development of hazard theory is briefed, and the structure and concept of hazards are analyzed. While further improving the definition of hazard, the classification of hazards and accident prevention and control model are explored. The position of each type of hazard in the accident control model is further analyzed. The causes of accidents and hazard theory-based measures are pointed out. It is believed that the research on hazard theory should be strengthened, especially the research on identification and control of direct hazard, the first triggering hazard and initial hazard, in anticipation to fully understand all types of hazard resulting in accidents, establish a complete set of hazard theory, and enhance the level of safety management and accident control in coal mines.
