The Truth is Stranger than Fiction

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 …

Block Caving Mining Method: Transformation and Its …

The first documented underground mine which applied the block caving method was the Pewabic iron mine in 1895 [43]. Although the block caving method has been known for over a decade, its massive deployment has only occurred in the last twenty years. During that time, the number of cave mining projects increased almost four times, from 17 to over

caving rate is constant (based on the use of a constant volume increase coefficient). Several case studies later showed that these assumptions were incorrect. Studies by Beck [6] at the Ridgeway Deeps Mine in Australia have shown that sometimes caving initiations may not occur on part of the undercut area.
