Block Caving: Mining Specialization | E & MJ
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.
Study of the Influence of Block Caving Underground Mining on …
Block caving mining method is one of the most viable and preferred mass underground mining methods for low grade orebody. However, in combined surface and underground mining, the breakthrough of an underground caving under an open pit may result in subsidence at the bottom of the pit. This can pose a serious threat for the …

The Ridgeway Deeps block cave is a new operation developed within Newcrest Mining Limited's Cadia Valley Operations, located approximately 20 km South West of the city of Orange in the NSW central west. The block cave forms the continuation of the existing Ridgeway sublevel cave (SLC) operation that has been actively mined since 2000.
An overview of block caving operation and available …
Block refers to the mining layout in which the ore-body is divided into large sections of several thousand square meters. Caving of the rock mass is induced by undercutting a block. The rock slice directly beneath the block is fractured by blasting, which destroys its ability to support the overlying rock.
