Bow-tie analysis of a fatal underground coal mine

Background: Bow-tie analysis combines aspects of fault-tree analysis and event-tree analysis to identify an initiating event; its causes and consequences; and potential preventive and mitigating control measures or barriers. Aims: The aim of the research is to analyse a fatality which occurred in a Queensland underground coal mine in 2007 to illustrate this technique.
