Abstract: Only had recieved the probability of each basic in the accident could the quantitative analysis of FT be went on, yet the events in large number of occupational accidents are of fuzzy events, the probabilition of which are incertitude. In this paper, Spontaneous Fire, the typical accident in colliery, was studied, and the method of fuzzy event FTA was adopted. In spite of the structure of Spontaneous Fire Fault Tree has been known clearly, the probability of events in the tree can not be recieved accurately. Nevertheless, during a long period of experimence in colliery, many experts can discern the possibility of the accident causes by linguistic variables, so that the useful information for FTA in those could be utilized. In this paper, on the thoery of Fuzzy and by the method of Delphi, 25 experts opinions on Spontaneous Fire were gathered, the probabilities of basic events were decided and the critical importance of events were put in order, the measures of prevention and control the accident were afforded.
