Fault Tree Analysis of Mining Gas Explosion Based on Trapezoid Fuzzy Number
With the fault tree analytic method to analyze the mining gas explosion, the probability of fault trees basic events is very difficult to determine. We describe the probability of basic events of fault tree with the analysis method of 3σ. Using the trapezoid fuzzy analysis method, we determine the importance of basic events, arrange their order and faintly classify two factors leading to gas explosion. Fuzzy analysis method has been found more and more extensive applications to the order of the basic events in fault tree and fuzzy mathematics analysis in finding the two factors leading to the mining gas explosion. Considering the fuzzy probability order and classification, we can find out basic events with bigger probability. If we want to control the mining gas explosion fundamentally, we must put an end to the occurrence of events with big importance. This is of vital significance for the coal mine decision-making management.
