The successful implementation of sublevel caving SLC at Ridgeway Gold Mine Ridgeway requires the technical aspects of caving and flow behaviour to be understood Cave propagation must be controlled and continuous to allow safe extraction of ore below The understanding and use of processes to manage granular flow behaviour are also required to ensure economic ,...

Sub-level caving is a highly efficient, top-down, underground bulk mining method Recent developments in sub-level cave mining have advanced the understanding of the technique and its production performance, which allow it to now be considered as a highly viable alternative to open stoping and, in some cases, even to block caving...

Raise caving, as opposed to sublevel caving, is a method that enables mining of the orebody from bottom to top, instead of from top to bottom In other words, the sequence is reversed, and the technology shift has several advantages, not least in terms of safety...
