Research on Cybernetics of Hazards and Its Applications in Prevention of Coal Mine Accidents

It is very important for accident prevention to find out the possible causes of the accident before it occurs. Based on the analysis of the natures of the accident, the theory of the accident trigger chain was put forward, which enriched the theory of accident causation. By combining the cybernetics with the accident trigger chain theory, the micro work safety hazard control theory was established, and on the basis of this theory, a "three-step" method for enterprise work safety was set up. By taking the hazard control system of the gob gas explosion accident in a coal mine as the example, the concrete work steps of this method was analyzed. The proposal of the hazard control theory can further improve and enrich the safety cybernetic, safety design, reliability and so on and provide a theoretical basis for the study of hazard control measures.
