摘要
Based on the basic principles of Bayesian networks and characteristics of hazards in coal mine,combining analysis of the mechanism of coal mine accidents,discussed the method to build Bayesian networks and transform fault tree logic structure into Bayesian networks ; and then the relationships among risk factors are expressed by Bayesian networks.According to the principle of the system safety analysis and evaluation,introduce the method to apply probabilistic reasoning to risk analysis and evaluation of hazards in coal mine.Using analysis of gas explosion accident as an example to describe the application process of the method,the result shows that it is an applicable method with intuitive form and efficient calculation for safety analysis and evaluation of colliery system.
