The block caving mining method has become increasingly popular in the last two decades. Meanwhile, Indonesia has several potential ore bodies which have not yet determined suitable mining methods ...
Abstract: Cave mining methods are becoming the methods of choice due to their potential to extract ore from large low-grade deposits at depth at production rates comparable to open pit mines. However, the high upfront capital related to the degree of development and time lag before production require detailed planning and reliable studies to cope with the …

Block caving does not cause uncontrollable environmental impacts, such as changes in landscape on the surface, especially in block caving mines in strong deep rocks. In some instances where the deposited deposits result from an open pit mine, it is necessary to conduct a comprehensive study to establish the optimal crown pillar geometry [ 133 ...
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. …
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 …
performance of new large caving projects. Over the last 20 years Newcrest has developed unique capabilities within the caving industry to efficiently mine deep and low-grade deposits, transitioning from Sublevel Caving in Ridgeway and Telfer during the early 2000's and more recently to Block Caving at Ridgeway Deeps, Cadia East PC-1 and PC-2.
The mine transitioned from a century-old open pit operation to an underground mine using the Macro-Block Caving Method to extract deep reserves and prolong the life of the mine for at least another ... summarized their experience establishing drawbells at Ridgeway Deeps and Cadia East operations.

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 …
mine design. 2 Methodology This section describes the methodologies used to evaluate four production level layouts that can be used in block caving. The base case considered to define the input parameters is a Chilean copper mine, where the El Teniente layout is used, with production drifts oriented N15°W of 4.2 × 3.9 m2 spaced 30 × 17.3 m2 ...
The success of the Ridgeway sublevel cave at Cadia Valley Operations (CVO) has led to expansion of block caving operations, initially at Ridgeway Deeps (RWD) and more recently at Cadia East panel cave mine. Cadia is one of Australia's largest gold mining operations, located in New South Wales, is characterized

either undertake block caving, divest the mine or cease mining at the end of pit life. Calder et al. (2000) uses the Palabora project as example of this. As a generalisation the authors find block caving is the preferred option above open pit cut backs when the grade of the orebody is above 0.5% Cu equivalent and
1 SUBLEVEL CAVING (SLC) 1.1 Basic considerations Sublevel caving is a mass mining method based upon the utilization of gravity flow of blasted ore and caved waste rock (Kvapil, 1998). It relies on the principle that ore is fragmented by blasting while the overlying host rock fractures and caves under the action of mine induced stresses and
