Abstract: The connotation and types of risk coupling of gas explosion accidents were defined on the physics, synergetics and catastrophology concepts. Moreover, hierarchical network model of risk coupling of gas explosion accidents was constructed from the perspective of risk emergence for a complex system. Then, coupled correlation of risk factors was analysed by using the N-K model. The result shows that gas explosion accidents are the consequence of stepping mutation from the nonlinear coupling between micro risk factors to macro hierarchical structural state, and the more the number of coupled risk factors is, the easier the gas explosion accidents are triggered. In the control process of risk coupling, risk coupling of objective factors is more difficultly controlled than that of the subjective factors.

Key words: gas explosion accidents, risk factors, risk coupling, hierarchical network model, N-K model
