Abstract:Mine fires break out and continue in confined scopes, studying mine fire dynamics characteristics is very useful to prevent and control fire. The judgement index of fire chaos characteristics was introduced, chaos analysis of mine fire process was described, and the reconstruction of phase space was also presented. An example of mine fire was calculated. The computations show that it is feasible to analyze mine fire dynamic characteristics with chaos theory, and indicate that fire process is a catastrophe, that is to say, the fire system changes from one state to another during mine fire.
Key words: mine fire; dynamic characteristics; state change
