Narrabri Mine has approval to use longwall mining methods to extract up to 11 Mtpa of ROM coal from the Hoskissons Seam within ML 1609.
The approved underground mining area encompasses a total of 20 longwall panels ranging in length between approximately 1.8 km and 4.0 km, depending on seam conditions and site constraints, and ranging between 295 m and 400 m wide.
The longwall design will be based on proven technology with an emphasis on reliability of equipment. The principal components of the system will include:
- Double-ended ranging drum shearer rated at 4,500 tph with full horizon control;
- An armoured face conveyor rated at 4,500 tph with provision for single tailgate drive and dual maingate drives;
- Beam Stage Loader rated at 5,000 tph; and
- High capacity two leg and four leg chocks shields with shearer initiation, base lift and high set functions.
Narrabri Stage 3 Extension
The Narrabri stage 3 extension project is an extension of the existing Narrabri underground mine.
On 1 April 2022, the IPC announced that it had approved the Narrabri Stage 3 Extension Project, subject to meeting a range of IPC conditions, including in relation to emissions mitigation technology and measures.
The project seeks to convert Narrabri’s adjacent Exploration Licence into a Mining Lease and use the existing portals, CHPP, rail loop and associated infrastructure to extract, process and export high-energy th ........
