摘要
Abstract
In the absence of adequate reliability data, Fuzzy Fault Tree Analysis offers an important way for the study of mine ventilation system reliability. To study the reliability of mine ventilation system, the fuzzy Fault Tree Analysis (FTA) was established for a mine in Cansu, with triangular fuzzy number as basic-event occurrence rate and " mine ventilation system fault" as top-event, based on perfect system composition. The results show that the large number of minimal cut sets is high to 549 for the first grade event named " monitoring the feedback system failure". The reliability of top-event and the first grade e-vent is low, with (0.009, 0.014, 0.009) of top-event occurrence rate and 2.3% of the most value. The highest fuzzy degree of weight is 0. 084 3 in the monitoring the feedback system failure , with the remainders varying from 0.005 0 to 0.010 0.关键词
