It found out minimal cut sets and minimal path sets by theory of Boolean algebra law method. It determined importance degree of structure of basic events through solving minimal cut sets and minimal path sets, so as to know degrees of danger and safety of coal mine and combination relation of basic cause events of gas accident and their importance. It also gave prevention measures of gas accident. Key words: coal mine, gas accident, gas explosion, FT A, Boolean algebra law method ( Fault 0 T ree Analysis, FT A) , , , , , ( ) , , ,
