Austar Coal Mine (Austar) is a deep underground coal mine located approximately 10km southwest of Cessnock in the Newcastle Coalfields of New South Wales, Australia.
Austar Coal Mine is owned by Yancoal Australia Limited, an Australian - Chinese partnership. Yancoal purchased the mine in December 2004 and renamed it Austar Coal Mine.
Austar commenced mining operations in April 2005 undertaking underground mining activities within the company's existing mining lease area and introduced a new technology called Longwall Top Coal Caving (LTCC) technology in September 2006.
Introduced in France, and further refined in China for the last 15 years, top coal caving uses a modified longwall mining system. LTCC technology is adeal in thick seams and enables significantly greater resource recovery is seams such as the Greta Seam. Austar has successfully used LTCC technology in Stage 1 to Stage 3 of the Austar Coal Mine.
