Ridgeway Gold and Copper Mine, New South Wales Mining

The Newcrest board approved development of the Ridgeway Deeps block cave in June 2007. 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.

Full-scale Flow Marker Experiments at the Ridgeway Deeps

May 09, 2016 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).

Block Caving groundtruthtrekking

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
