Austar Coal Mine August 2016 A pressure bump of significant intensity was immediately followed by a "dynamic" ejection of coal from the longwall B2 face during production at Austar Coal Mine on 19 August 2016. The ejection of coal from the face resulted in two workers being knocked to the ground and struck by small pieces of coal.
Oct 18, 2017· coal burst potential has been identified, due to the presence of geological structure or change in stress regime, control measures should be implemented that remove workers from the place of risk.

regional seismic event, nor does every mineinduced, regional seismic event manifest itself as a coal outburst at the seam level. In reality, coal bumps are just one subset of mineinduced seismicity, and like mineinduced nonbump events, they can exhibit a wide range of magnitudes and energy release.

The Austar Coal Mine is a coal mine located near Paxton, New South Wales. The mine has coal reserves amounting to 221 million tonnes of coking coal, one of the largest coal reserves in Asia and the world. The mine has an annual production capacity of 3 million tonnes of coal, and employs 409 people.
The Greata seam, in the area of the Austar Coal Mine, is a thick seam and thus by using this mining method, up to 80% of the additional coal can be accessed, which would otherwise be lost." The coal is exported through the Port of Newcastle, New South Wales.
