Full-scale Flow Marker Experiments at the Ridgeway Deepsand …

Full-scale marker experiments at Cadia Valley underground operations have been ongoing for over 14 years. Initial marker experiments were undertaken in the Ridgeway sublevel cave (RW) (2002), and subsequently at Ridgeway Deeps (RWD) (2008) and Cadia East PC1 (CEPC1) (2012) block caves. Over 25 000 markers have been installed at the three caving operations to date …

Debottlenecking of the Ridgeway Concentrator at …

The Ridgeway Concentrator at Newcrest Cadia was commissioned in 2002 as an ABC circuit to treat the ore from the Ridgeway sublevel cave (SLC) at around 5 MTPA. Consisting of a single pinion 32' autonomous grinding (AG) mill and a single pinion 7 MW ball mill, it was a much smaller plant than the adjacent Cadia Hill Concentrator. Subsequent expansion of the circuit saw …

Mine Details | MiningLink.au

The Ridgeway mine is worked by means of a block and panel caving method of underground mining. Ridgeway Mine is now known as Ridgeway Deeps Mine Mining at the Ridgeway underground mine has undergone transition to the Ridgeway Deeps deposit. Ridgeway Deeps is located below the original Ridgeway gold deposit that was initially exploited.

Applying a ground support and reinforcement design methodology

It sets out to describe the benefits of following a methodology, provides a broad format for ground support and reinforcement design, and the steps undertaken to apply the methodology at Ridgeway Deeps. At the time when ground support was being designed the Ridgeway Mine was in the process of transitioning from sublevel cave to block cave mining.
