Full-scale Flow Marker Experiments at the Ridgeway Deeps …
— 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 …

In mid-2008, the facilities were upgraded to suit predictions of harder and fines-deficient ore from Ridgeway Deeps block cave mine. The upgrade included installation of a secondary crushing circuit and additional regrind mill power. A 2.24 MW Vertimill was installed in 2011 to reduce flotation feed size and improve metal recoveries.

— 1. Introduction. Block Caving is an underground mining method in which high productivity and low operational costs are expected when applied to thick low-grade ore bodies. 1, 2 Using this process, the broken ore is extracted from the bottom of the ore body after the initial undercutting. The undercutting induces progressive rock mass caving due …

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.
