However, sublevel caving mining inevitably results in the formation of underground goafs, and the existence of underground goafs will cause the imbalance and redistribution of the stress around the opening, which will cause the displacement, deformation, and failure of the roof strata [5, 6].
Mining often involves a fully selfreliant site production operation. Low grade metallic ore is mined underground by caving or from the surface by open pit . The hoist and headframe building will be located at the main shaft, with ore Crushing and grinding involves rotating and tumbling ore to increasingly smaller sizes.
Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining.
Caving Underground Mining Methods (longwall, Sublevel caving, Block caving) 1. This material is intended for use in lectures, presentations and as handouts to students, and is provided in Power point format so as to allow customization for the individual needs of course instructors.
Block caving method 1. Block Caving Method Virendra Suryawanshi 2. Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving.
Sublevel caving is a systematic method and uses regular layouts and working procedures. ... Hole deviation increases with hole length with sublevel height. Drilling costs increase with hole length. ... In this case many samples are taken and assayed underground in order to determine the percentage of ore in any particular bucket load.
Some of the world's major mining companies, currently comfortably mining from large efficient open pits, are looking into the future when these pits come to an end. To maintain a competitive position on the cost curve, these organisations will have to take open pit efficiencies underground. Only caving methods can challenge open pit efficiencies.

method of underground mining In mining: Sublevel caving This method owes the first part of its name to the fact that work is carried out on many intermediate levels (that .
Block caving is an underground mining method that uses gravity to exploit massive, steeply dipping ore bodies located at depth. These ore bodies are generally low grade in nature and are too deep to be extracted through open pit mining.
Sublevel caving at our Ridgeway mine in New South Wales (currently on care and maintenance) and at Telfer in Western Australia has produced strong results. Panel caving is used at Cadia East in New South Wales and it is anticipated that similar continuous mining systems will be applied at the WafiGolpu project in Papua New Guinea.

Resolute Mining has reported the results of an updated prefeasibility study (PFS) for underground mine development below its current openpit Syama gold mine in southern Mali. The updated PFS assumes development of a largescale sublevel caving operation and confirms that an early move to underground mining in 2016 will produce robust economic returns.
