Airly Coal Mine is an underground coal mine located within the Sydney Basin, approximately 171 kilometers north of Sydney, 40 kilometers northnorthwest of Lithgow, and 4 kilometers northeast of Capertee.
Airly Mine was initially owned by Novacoal from 1993 to 1997, when it was sold to Centennial Coal. Centennial Coal began construction in March 1998 and mined until the mine moved to a care and maintenance phase in January 2013. The first expiration date of the mining lease was set for October 2014.
The mine re-opened in February 2014, and coal production recommenced in March 2014. The mine has been designed for a life of 25 years from 2009 at 1.8 Mt/year. However, at a 2019 Community Consultative Committee meeting for the Airly mine, mine officials announced their goal of increasing yearly production to 3 Mt/year.
In August 2015, the lease was modified to extend until April 2016. The company then requested an extension to the mine for 20 years of additional mining followed by 5 years of decommissioning and rehabilitation. This was approved in December 2016.
The Airly mine operation uses a continuous miner system to extract coal from underground. On-site facilities include a coal handling and preparation plant (CHPP), as well as a rail loop and loading facility for rail transport to Port Kembla.

Environmental groups protested an extension of the Airly Mine’s permit by 20 years, a move that was approved in 2016 by the Planning Assessment Commission. The PAC allowed the public to submit comments of opposition or support of the mining extension; they gathered 412 objections and 97 submissions in support.
Environmental groups argue that continuing mining would destabilize pagodas and cliffs that form part of Capertee Valley, which is Australia's largest canyon.
"I'm calling on the PAC to apply the precautionary principle to make sure that the tip of Genowlan Point … doesn't fall into the Capertee Valley and go extinct, and also at the same time damage the ecotourism industry," said Haydn Washington, a visiting fellow at the University of New South Wales' Institute of Environmental Studies, at a public PAC meeting in 2016.
