Modeling and analysis of the risk evolution for coal mine gas explosion from the perspective of safety information loss

To reveal the causal mechanism of coal mine gas explosion accidents, taking coal mine gas explosion accident cases as the research object, and combining in-depth analysis of the process of safety information transmission and safety information loss, a coal mine gas explosion safety information transmission loss model was constructed. In addition, the causal factors of gas explosion accidents were extracted from six stages: loss of safety information generation, transformation, perception, cognition, decision-making, and execution. Finally, using complex network theory, a weighted network model for the evolution of coal mine gas explosion risk is established to explore the key risk factors and evolution paths of gas explosion accidents, and to reveal the causal mechanism of coal mine gas explosion accidents from the perspective of safety information loss. The research results indicate that the proportion of safety execution losses during the accident stage is as high as 28.08%, followed by safety awareness losses. In addition, 5 key risk factors and 3 key evolutionary paths were identified.
