With its production level at a depth of 1,050 m, Newcrest Mining developed Ridgeway Deeps beneath the existing sub-level caving mine. The transition took place in 2009, although as a 2012 analysis note from Credit Suisse suggested, the move here did not go completely to plan. "The caving rate and fragmentation is in line with modeled projections.

caving rate is constant (based on the use of a constant volume increase coefficient). Several case studies later showed that these assumptions were incorrect. Studies by Beck [6] at the Ridgeway Deeps Mine in Australia have shown that sometimes caving initiations may not occur on part of the undercut area.
