| Abstract: | This text builits up the coal gas explosion fault tree,first,the minimal cut sets are used to do qualitative analysis of the coal face gas explosion,gets the structure importance of each basic affairs;then,uses the minimal path sets to cary on the quantitative analysis so as to get the top accident occurrence ratio calculation formula;finaly,gives the suggestion for preventing and curing gas explosion. |
