Ridgeway Gold and Copper Mine, New South Wales -

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. Ridgeway Deeps was developed at a cost of A$525m by Ausenco. The project involved construction of a block cave, extension of the existing underground ore-handling

The new block cave was located below the sub-level cave mining with all personnel, plant and equipment required to be transported via an eight kilometre decline through the operating mine. All connections to existing infrastructure had to be co-ordinated to suit the existing mine shutdown schedule.

Block Caving: Mining Specialization

Diering and Nat Burgio from Stratavision in Australia co-authored a paper on the use of PCBC software for modeling the Ridgeway Deeps block cave, which they presented at the MassMin 2008 conference in Luleå, Sweden. With the trend toward the establishment of block caves at greater depths over relatively small footprints and in competent rock-mass environments, they noted that operators are ...

Ridgeway gold mine Report Wood Mackenzie

Ridgeway is an underground copper/gold mine which is located 3km north west of Newcrest's Cadia Hill open pit mine. The mine is undergoing a transition to block caving which will see production levels reach 6Mt/a ore by 2012. In October 2012 Newcrest indicated in a corporate presentation that ore feed from Ridgeway underground mine will cease in 2015 with the depletion of Lift 1. Stated ...

Mining Methods: Block Caving Geology for Investors

26/03/2021  In some mines, there are multiple block caving events, such as at the Ridgeway mine in Australia, when the initial block cave was depleted they went deep (1100 metres below surface) for their second block cave. In other cases such as Cadia, Palabora and Chuquicamata block caving was the solution to extending mine life when the open pit resources ran out. The Globe Miami mine is

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. It was also recognised that experience with techniques and methods of cave ...

Block caving - QueensMineDesignWiki

Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining. The technique is commonly used to extract low grade copper, copper-gold, iron and molybdenum ores although there are other applications. Due to the low cost ...

Underground mining (hard rock) - Wikipedia

Block caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving rock to fall into. The orebody is drilled and blasted above the undercut, and the ore is ...

Block caving: A new mining method arises

25/07/2018  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. This broken ore falls into a pre-constructed series of ...

Production resumed in 2000 using the block-cave method and is at the 3,110-meter elevation level. The DOZ is a mature block-cave mine that previously operated at 80,000 metric tons of ore per day. Current operating rates from the DOZ underground mine are driven by the value of the incremental DOZ ore grade compared to the ore from the DMLZ and Grasberg Block Cave underground mines.
