ABSTRACT: Forty one basic events leading to the coal mine gas explosion accident are identified by means of FTA (Fault Tree Analysis). On the basis, 81 minimal cut sets and 5 minimal path sets are obtained in the occurrence of gas explosion accident within coal mine through boolean algebra method. By calculation of minimal cut sets and minimal path sets, the structure importance of each basic event is determined, and thus clearing the degree of risk (safety) of accidents, and mastering the combination relation and important degree of every basic reason events resulting in the gas explosion accident; measures for the prevention and control of gas explosion accidents are proposed.

Keywords : Gas explosion; Fault tree; Minimal cut set; Minimal path set; Structure importance.
