A variety of different blocks occurring in an underwater coral reef; sand can be seen lining the ground, cut sandstone in underwater ruin structures and various forms of coral. Blocks are arranged in a 3-dimensional grid of 1-cubic-meter cells, although some blocks appear to occupy a partial cell; these include slabs, snow layers, ladders ...
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 additional infrastructure added as the ore source transitioned to Ridgeway Deeps, a block cave below the original Ridgeway SLC.
This paper provides an overview of a new granular flow-deformation simulation technique based on a coupled Newtonian Cellular Automata (NCA) representation of the cave muckpile with an explicit Discontinuum Finite Element (DFE) model of the rock mass. The method emerged from the need to study the impact of draw and gravity flow on the initial …

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 …
"The Ridgeway Deeps mine will use the block caving technique to extract the gold and copper bearing ore. It is a very cost-effective way to mine, using gravity and in-situ stresses to break up ...
The Ridgeway gold mine has been an enigma of the international underground hard rock community for nearly 20 years. It nearly didn't eventuate as it was more than 500 m below a farmer's paddock in Central New South Wales when the exploration team, looking for open pit deposits, got a sniff on its last attempt and then drilled the high-grade discovery hole. …
Block cave fragmentation has been documented in the literature to have a significant impact on mine design, performance and downstream material handling and comminution processes. Due to this impact, emphasis is placed on the premining prediction and subsequent quantification of primary and secondary fragmentation distribution. This …
The Ridgeway underground sublevel caving mine commenced production in 2002 and expanded into block cave mining in 2009. Ridgeway is a vertical porphyry copper/gold …

The Ridgeway Deeps Lift 1 block cave operation was mined between 2007 and 2015 and was Newcrest's first block cave operation. The change to block caving was introduced after the identification that the grade profile for Ridgeway was declining to the point where subsequent SLC levels below the 5040 mRL were uneconomic.
