This paper discusses the fragmentation prediction and assessment methodology employed at the Ridgeway Deeps (RWD) and Cadia East PC1 (CEPC1) cave operations.Prediction of drawpoint fragmentation was based on an iterative process, which relied on an improved quantitative and qualitative understanding of the rock mass as the mining project developed. In particular, the collection of scanline ...

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 associated risks.
Learning Deep Disentangled Embeddings with the F-Statistic Loss Karl Ridgeway, M. Mozer Published 1 February 2018 Computer Science ArXiv Deep-embedding methods aim to discover representations of a domain that make explicit the domain's class structure. Disentangling methods aim to make explicit compositional or factorial structure.
Feb 25, 2021I finally walked into the house of the New Republic magazine and was ushered up the stairs to a young Ridgeway deep in thought at his typewriter. He looked at me, saying he just had a few minutes. Well, his curiosity resulted in a major article titled "Car Design and Public Safety." The next year, he broke the fuller story titled "The Dick" about GM and its detectives tailing me ...

Ridgeway Deeps is Newcrest Mining's first panel cave project. Ridgeway Deeps have made use of prior experience in panel caving elsewhere to design their drawbells and undercut but have taken the designs to a higher and more challenging level. The challenging drawbells were both higher and wider. The rings weIMGP5521re more angled with a negative …

The Ridgeway Deeps mine is expected to produce over 2.8M gold equivalent ounces (1.6m ounces of gold and 210,000 tonnes of copper) over the total project life of 12 years.
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. Over 3,000 ...

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.
