Despite many publications on FTA, few studies have been devoted to the fuzzy fault tree analysis (FFTA) technique for underground coal mine methane explosion. First, in this study the fault tree of coal working face and heading face was used to analyze the influential factors and processes of coal .
Fault Tree Analysis. Fault Tree Analysis (FTA) is a popular and productive hazard identification tool. It provides a standardized discipline to evaluate and control hazards. The FTA process is used to solve a wide variety of problems ranging from safety to management issues.
And fault analysis of the pantograph is used to establish the fault tree. The Petri net model of the pantograph is simplified on the base of the principle of duality and resorption by combining the modeling theory of Petri net and the fault tree. The minimum cut set is obtained by solving the above simplified model with incidence matrix.
