Appin Mine Ventilation and Access Project

The Appin Mine in the Wollondilly region of New South Wales is an existing underground mine, primarily producing metallurgical coal. It is currently operating in the Douglas Park and Menangle areas.

An integral requirement of underground mining is adequate ventilation and mine access, to ensure a safe and efficient working environment for our people.

As Appin Mine moves further from existing surface infrastructure, we are constructing future infrastructure to support the mine which includes Ventilation Shaft No. 7, Ventilation Shaft No. 8 and mine access facilities. The infrastructure will be located at 345 Menangle Road and is known as the Appin Mine Ventilation and Access Project.

Ventilation Shaft No. 7 will be a downcast shaft, drawing fresh air into the mine. It will also double as an entry point to the mine for our people.

Ventilation Shaft No. 8 will be an upcast shaft, drawing air out of the mine.

Ventilation Air Methane Abatement Project

GM³ has submitted a modification to its existing Bulli Seam Operations Project Approval (MP 08_0150) to develop and operate a ventilation air methane abatement demonstration plant, adjacent to Appin Mine’s Vent Shaft No. 6.

The Project aims to enable further greenhouse gas (GHG) abatement of ventilation air methane from Appin Mine. The demonstration plant will use a Regenerative Thermal Oxidiser (RTO) to convert methane (CH4) into carbon dioxide (CO2) and water through oxidisation. This is an established, proven design that is used worldwide.

With methane having 28 times the global warming potential than (CO2), VAM abatement offers GM³ a significant opportunity for emissions reduction.
