[Abstract] 
Key Conclusions:
fiogf49gjkf0d
The energy analysis presented in this paper can help to improve the understanding of energy release mechanisms especially under Australian conditions.
Key Findings:
fiogf49gjkf0d
Numerical modelling study is conducted to evaluate the roles and contributions of difference energy components, namely stress and in situ gas.
Objective of the Paper:
fiogf49gjkf0d
This paper aims to examine the mechanisms contributing to coal burst occurrence, with an emphasis on the energy release concept.
Problem Statement:
fiogf49gjkf0d
Coal burst is a dynamic release of energy within the rock (or coal) mass leading to high velocity expulsion of the broken/failed material into the mine opening. This phenomenon has been recognised as one of the most catastrophic failures associated with the coal mining industry, which can often lead to injuries and fatalities of miners as well as significant production losses.
