Austar Mine is the first mine in Australia to successfully implement the Longwall Top Coal Caving (LTCC) mining method. The mine is extracting the Greta Seam of 6 m thickness at a depth of approximately 520 m. The main overburden unit is the Branxton Formation which is massive and strong (fine to medium sandstone/silty sandstone/pebbly bands).
The mine . Austar Coal Mine (Austar) is a deep underground coal mine located near Paxton about 10 kilometres south west of Cessnock in the Hunter Valley, NSW. Production in the Greta seam (4m thick) is achieved using the Longwall mining method and bolter-miners used for roadway development. The mine produced 1.64 Mt of raw coal in 2013-14. iii

Typically,
This report has downloadable files containing asset level detail for the Austar coal mine. The aim of Wood Mackenzie's coal mine analysis is to provide a detailed review of the key technical, commercial and economic issues surrounding the historic and future development of a mine. Although not all mines have cash flows, where applicable, cash ...

seismic survey to a coal mine. INTRODUCTION Seismic reflection data have been acquired for coal mining operations in Australian coal basins for over 30 years. Originally used solely as a resource exploration tool, the seismic method now routinely contributes to coal-mine design and development. In the decades since seismic ...
Tragedy at Depth: Austar Coal Mine double fatality. The following is the executive summary of an investigation report, prepared by the NSW Mine Safety Investigation Unit, into a double fatality at the Austar Coal Mine in New South Wales in 2014. At 9.05pm on 15 April 2014, James Mitchell, 49, and Phillip Grant, 35, died when a major rib ...
Austar Coal Mine is an underground longwall coal mine located near Cessnock in the Hunter Valley of New South Wales (NSW), Australia and is the only underground mine still extracting the Greta Seam in this region. The mine was the first in Australia to adopt the Chinese-developed longwall top coal caving (LTCC) method for thick seam extraction.
Austar. Austar is one of the oldest mines within New South Wales, had been in operation for nearly 100 years. Yancoal ownership - . The Austar coal operation was placed in "Care and Maintenance" in March 2020, and is now transitioning to closure, which will include extensive rehabilitation.

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. In 2012, he mine has an annual production capacity of 3 million tonnes of coal, and employs 409 people. This colliery incorporates the former Pelton, Cessnock (Kalingo) and Ellalong ...

Coal burst has been recognized as a serious risk for Australia's underground coal mines following a fatal coal burst accident at the Austar Coal Mine [6, 7]. Because of lacking coal burst ...
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.
In coal mines, strain bursts are also referred to as coal bursts. In Australia, a number of such events were reported in recent years, including the one which led to a double fatality at the Austar Mine in 2014. For forecasting of seismic events in coal mines, the first step is to know the nature and location of such faults, relative to the ...
