Abstract: To research fully the causation mechanism of extraordinary serious gas explosion accidents, the statistical analysis method was used for idenifying the core conditions, difference conditions and enlargement conditions of general gas explosion accidents. Then, evolution mechanism model was built for extraordinary serious gas explosion accidents after analyzing the relationship among the core conditions, difference conditions and enlargement conditions. The model was used to analyze the Chenjiashan accident. The results show that extraordinary serious gas explosion accidents were based on the core conditions of the general gas explosion accidents, which interact with difference condition and enlargement condition, and that the prevention of extraordinary serious gas explosion accidents requires perfecting the laws and regulations, and the enterprises to attach great importance to establishing their risk pre-control system of human-machine-environment-management.

Key words: coal mine, gas explosion, extraordinary serious accidents, accident mechanism, defense-in-depth management model, human error correction model
