Ridgeway Gold and Copper Mine, New South Wales - Mining ...

The Ridgeway Deeps block cave project involved development of resources below the Ridgeway Underground mine at a depth of 300m to about 1,100m. It is the first natural caving operation and the deepest block cave in Australia. Ridgeway Deeps was developed at a cost of A$525m by Ausenco.

The Effects of Faults on the Mechanics of Cave Propagation ...

My research aims to further the understanding of the mechanics driving the caving process with particular focus on how large fault structures are influencing caving. I will be back analysing how the Ridgeway Deeps block cave has evolved using fully-immersive 3D virtual reality to analyse mine evolution, closely linked to time.

Full-scale Flow Marker Experiments at the Ridgeway Deeps ...

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 approximately 20 000, 3000 and 2500 for RW, RWD and CEPC1 respectively .

Ridgeway gold mine Report Wood Mackenzie

Ridgeway is an underground copper/gold mine which is lo ed 3km north west of Newcrest& 39;s Cadia Hill open pit mine. The mine is undergoing a transition to block caving which will see production levels reach 6Mt/a ore by 2012.

Newcrest increases mine caving technique

Block caving is being used for the Ridgeway Deeps deposit and a block cave variation called sub-level caving will be applied at the Cadia East operation, which will become Australia’s largest ...

of the Ridgeway sublevel cave. The success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations. What makes Cadia unique is the high-stress, hard rock mining conditions combined with the ability to

Block Caving: Mining Specialization E and MJ

In addition to learning from Ridgeway, Newcrest also sought technical expertise in block and panel caving from other world players, including Codelco and Rio Tinto’s Northparkes. As the Credit Suisse report noted, “Ridgeway was very much the early prototype cave for Newcrest and has clearly shown what should not be repeated and what can be improved.”

Mining Methods: Block Caving Geology for Investors

Finally, when block cave mining is up and running, there is noticeable ground subsidence in the immediate vicinity. Lastly, there is substantial risk of pit slope failure over block caving as shown by the pit wall landslides at Palabora, Bingham Canyon, Cadia and Chuquicamata.
