Developing coal burst propensity index method for Australian coal mines
International Journal of Mining Science and Technology, 2018 Coal burst is the violent failure of overstressed coal, and it is often accompanied by sound, coal ejection and seismic events. It is subsequently recognized as a serious safety risk of Australia after double fatalities coal burst happened at Austar Coal

Numerical Study on Coal Burst Proneness Characteristics of Fissured Coal Mass
Lithosphere, 2022 Coal burst proneness of coal mass is a leading factor of coal burst which is influenced by fissures. In this paper, the elastic strain energy (ESE) and residual energy index (REI) were used as coal burst proneness indicators.

Microseismic comprehensive evaluation method for coal burst: a case study in the Zhaolou Coal Mine. [PDF]
Sci RepAbstractTo explore the multiparameter precursor characteristics of pre- and post-coal burst. Based on a coal burst of LW 1305 in the Zhaolou Coal Mine, an early warning method combining stress‒strain curve and microseismic multiparameter is proposed. The research results show that coal burst was induced by the intrinsic static high-stress concentration
