Abstract: The FTA-AHP method is used to analyze the mine blasting fly-rock injury accidents, the blasting fly-rock injury accident tree is built, according to the FTA method,the hierarchical model is constructed, the judgment matrix is obtained by introducting the ratio of structure importance of basic events in FTA method, so, the order of each basic events is caculated.Compared with the FTA method, the FTA-AHP method is capable of distinguishing the influence degree of each basic event to the top event so as to prevent and control the occurrence of the accidents more effectively.

Key words: Fault tree analysis(FTA) , Analytic hierachy process(AHP) , Mine blasting, Fly-rock injury
