摘　　要：鉴于煤矿瓦斯爆炸事故风险传导关系迄今未被准确描述和细致分析,提出瓦斯爆炸事故风险耦合分析法。运用复杂系统理论,界定瓦斯爆炸事故的风险耦合的含义及类型,并借鉴物理学中触发器的概念,讨论瓦斯爆炸事故风险传导的路径及内在机理,从风险涌现角度构建风险耦合层次网络模型。结果表明,瓦斯爆炸事故是瓦斯动力系统内外部因素风险耦合作用的结果,其演化过程是微观风险因素间的非线性耦合导致宏观层级结构状态发生阶跃式突变。In view of that risk conduction process has not been described accurately and analyzed in detail for gas explosion accidents in coal mines the paper was aimed at working out an analysis method of risk coupling for the accidents. A definition of risk coupling was given form a viewpoint of the complex system theory. Paths of risk conduction were discussed for gas explosion accidents by weaus of triggers in physics.A hierarchical network model was built for risk coupling form a viewpoint of risk emergeing.The result shows that gas explosion accident is the result of risk coupling action of gas dynamic system internal and external risk factors,and that the process of evolution is charaterized by steping mutation taking place in the macro hierarchical structural state,resulted form nonlinear coupling between micro risks.
