Abstract: To simulate fire spreading along underground tunnel system and smoke distribution process during an underground mine fire disaster，a new computer simulation method based on cellular automata and particle system theory is proposed.Considering special environment in an underground mine’s tunnel system，a cellular automata model，whose neighborhood radius is variable to simulate flame spreading，is employed；simultaneously a smoke model based on particle system using burning cells as launchers of smoke particles to describe smoke diffusion is introduced.The whole system runs based on a same clock.Time，space，and behaviors of flame and smoke are effectively combined together to obtain a better visual result.Accordingly，it can not only produce a sense of reality about tendency of fire spreading and motion of smoke，but also attain a large amount of information about real tunnel environment by recording spread distance of fire and quantities of smoke particles，all of which can provide a basis for fire prevention and control and also provide a decision-making support for workers evacuation.
