We have fault tree analysis on coal mill,Jan 01, 2019183 Coal burst triggering mechanism can be divided into selfinitiated 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 withlogical gates to analysis probability of undesirable or top event.

A fault tree analysis is a systematic and stylized deductive process in which an undesired event, such as a catastrophic failure of a system, is defined and then broken down to its individual causes. The very top of the diagram is the event and branching from it are its immediate causes.

The fault tree analysis module is based on sets of rules and logic symbols from probability theory and Boolean algebra. Gates represent logic operators that link the various branches of the fault tree together and determine whether the top event can occur or not. Basic events can be defined as the lower level events in each fault tree branch.
