Fuzzy fault tree analysis for gas explosion of coal mining ...

2018-8-14  In 1962, fault tree analysis (FTA) has been extensively employed as a powerful technique in risk analysis studies at Bell Telephone Laboratories in the United States. 1 Pan and Yun 2 introduced the logic gate into fuzzy theory. In this article, the “and” and “or” gates have been used to establish the fault tree.

Fuzzy fault tree analysis for coal burst occurrence ...

2019-1-1  Coal burst triggering mechanism can be divided into self-initiated and remotely triggered. One of the methods, which are used in system risk evaluation, is fault tree analysis. Fault tree is a top down, deductive failure analysis, which series of basic events combined with logical gates to analysis probability of undesirable or top event.

Using Fault Tree Analysis to Focus Mine Safety Research

2012-8-30  Fault tree analysis is a systematic safety analysis tool that proceeds deductively from the occurrence of an undesired event (accident) to the identification of the root causes of that event. On e recurring mine safety pr ob lem— a dozer falling into a void over a drawpoint on a coal surge pile—was analyzed using available, inexpensive ...

Fuzzy fault tree analysis for coal burst occurrence ...

Therefore, occurrence of coal burst as a top event in fault tree has been analyzed using fuzzy fault tree analysis. According to the results, occurrence probability values of coal burst with self-initiated and remotely triggered mechanisms are 0.9% and 11.6%, respectively in coal mines. In addition, the critical paths that lead to coal burst ...
