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. …

Bow-tie analysis of a fatal underground coal mine ...

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. One recurring mine safety problem - a dozer falling into a void over a drawpoint on a coal surge pile - was analyzed using available, inexpensive fault ...

Despite many publications on FTA, few studies have been devoted to the fuzzy fault tree analysis (FFTA) technique for underground coal mine methane explosion. First, in this study the fault tree of coal working face and heading face was used to analyze the influential factors and processes of coal mine gas explosion.

Fault Tree Analysis (FTA) and Event Tree Analysis (ETA)

Fault tree analysis (FTA) is a top-down, deductive failure analysis in which an undesired state of a system is analyzed using Boolean logic to combine a series of lower-level events. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) …

causes of fire in coal mines,flour mills

This paper presents a fault early warning approach of coal mills based on the Thermodynamic Law and data mining. The Thermodynamic Law is used to describe the working characteristics of coal mills and to determine the multi-parameter vector that characterize the operating state of the coal mill.

Reliability Assessment of a Co-Generation Power Plant in a ...

demonstrated the use of Failure Modes and Effects Analysis, and Fault Tree Analysis, to study power systems in coal mine shuttle cars in the United States. In the UK, the overwind at Markham Colliery in 1973, prompted research into the reliability of winding gear. The recommendations that resulted from this research considered

Application of fault tree analysis to coal spontaneous ...

Fault Tree Analysis (FTA) In many cases there are multiple causes for an accident or other loss-making event. Fault tree analysis is one analytical technique for tracing the events which could contribute. It can be used in accident investigation and in a detailed hazard assessment.

Root Cause Failure Analysis Of Coal Mill Vertical Shaft

Sand casting operations, though commonplace, pose a significant threat of explosion accidents. This paper presents a novel sand casting safety assessment technique based on fault tree analysis, Heinrich accident triangle, hazard and operability–layer of protection analysis (HAZOP–LOPA) and bow tie model components.
