Block cave fragmentation has been documented in the literature to have a significant impact on mine design, performance and downstream material handling and comminution processes. Due to this impact, emphasis is placed on the premining prediction and subsequent quantification of primary and secondary fragmentation distribution. This paper …

At present, intermediate-scale structure, anisotropy, mineralogy and model uncertainty may be neglected or under-represented despite their likely significant role in the mechanisms of cave propagation.Insights from an analysis of the Ridgeway Deeps block cave mine are discussed in this paper.CITATION:Murphy, T, Webster, A and Chitombo, G, 2016.
Ridgeway Deeps is a block cave (BC) located down dip of the operating Ridgeway sublevel cave (SLC) mine. The BC is located approximately 210 m vertically below the lowest SLC level and …

The Ridgeway mine is worked by means of a block and panel caving method of underground mining. Ridgeway Mine is now known as Ridgeway Deeps Mine Mining at the Ridgeway underground mine has undergone transition to the Ridgeway Deeps deposit. Ridgeway Deeps is located below the original Ridgeway gold deposit that was initially exploited.

Initial exploration pointed to an underground mine similar to Ridgeway Deeps, however, more recent drilling has revealed that a much larger zone of mineralisation exists, likely to support both underground and open cut mines. The Cadia Hill gold-copper porphyry deposit was discovered by Newcrest Mining in 1992. Cadia East was then discovered in ...

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 to stress redistribution and gravity.

Underground bulk mining methods such as Block Caving (BC) and Panel Caving (PC) are increasingly regarded as low cost solutions to extracting large, low grade underground metalliferous orebodies. Significant technological advancements in the last few decades have …
The Ridgeway Deeps Block Cave is located directly beneath the existing Ridgeway Sublevel Cave Mine. The selection of the material sizing and mine dewatering systems are important elements in the development of a large-scale, high tonnage (greater than 4 Mt/a) underground hard rock mine. The sizing system will influence the size and type of the ...
Cadia Valley Operations (Cadia) embarked on a path of cave mining in the early 2000s with the establishment of the Ridgeway sublevel cave. The success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations. What makes Cadia unique is the high-stress, hard rock …
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 …
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 installed at the three caving operations to date …

It sets out to describe the benefits of following a methodology, provides a broad format for ground support and reinforcement design, and the steps undertaken to apply the methodology at Ridgeway Deeps. At the time when ground support was being designed the Ridgeway Mine was in the process of transitioning from sublevel cave to block cave mining.

The Ridgeway gold mine has been an enigma of the international underground hard rock community for nearly 20 years. It nearly didn't eventuate as it was more than 500 m below a farmer's paddock in Central New South Wales when the exploration team, looking for open pit deposits, got a sniff on its last attempt and then drilled the high-grade discovery hole. It took …

According to , that success led to Rio Tinto adopting Automine for its Argyle block cave. Newcrest also uses it at its Ridgeway Deeps mine, while 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.
The success of that mine led to a significant expansion into block caving operations, first at Ridgeway Deeps, and then to the now established Cadia East operations. What makes Cadia unique is the high-stress, hard rock mining conditions combined with the ability to maximise investor returns through the use of very high lift heights at depths ...

The Ridgeway underground mine was developed shortly afterwards and commenced production in 2002, with Ridgeway expanding into block cave mining in 2009 (Ridgeway Deeps). Ridgeway was placed on care and maintenance in March 2016 with minor production resumed during 2017 to supplement plant feed following the Cadia East seismic event in April 2017.
