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).

According to Sandvik, that success led to Rio Tinto adopting Automine for its Argyle block cave. Newcrest also uses it at its Ridgeway Deeps mine, while Sandvik has delivered 14 LH517 LHDs, all equipped for autonomous operation, for Cadia East. Meanwhile, Northparkes’ reliance on its surface-operated LHDs is continuing to pay off.

Block caving. 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 ...

Full scale near field flow behaviour at the Ridgeway Deeps

Full scale marker experiments were designed and implemented at the Ridgeway Deeps block cave mine from March 2008 to October 2010. The experiments aimed at quantifying and assessing the geometry of the extraction zone, development of the extraction zone over time, variability of flow behaviour, and factors affecting flow behaviour in both the near and far field of the cave column.

The use of block caving to mine deep, massive, low-grade ore bodies is gaining increasing attention from the mining industry given its merits in terms of safety, tonnage produced and costs that can match those of open-pit operations. However, the undercutting and bulk extraction of ore through caving (Kendorski, 1978; Brown, 2003), leads to the ...

The role of block caving Although the caving mining system was initially used for shallow orebodies, it has recently been applied at depths of 2km underground. According to Suorineni, “caving heights have also increased drastically from about 200m to 500m”, creating so-called ‘super caves’.“There is insufficient experience caving in these environments,” he adds, which is a ...

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. The DOZ fleet consists of 186 pieces of mobile equipment.
