An overview of a wireless blasting system for use in sublevel caving operations that significantly reduces the risk posed to mine workers.S ublevel cave slc mining is breaking ore-bearing rock through blasting and drawing it out under the waste rock that is caving into the void created.Slc mines have the most intensive blasting process of all the mining methods, as generally one or two.
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.In block caving, a large section of rock is undercut, creating an artificial cavern.
This method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent.The production for a mine using sublevel stoping can range from 15- 40 tonsemployee-shift, while one stope can produce greater than 25000 tons per month.Mid-range mining cost relative cost 20.
Petra utilises this mining method to supplement block caving, in order to provide production flexibility.For example, at the finsch mine sub-level caving is being used as part of the mines expansion programme to maintain underground production levels during the transition from the block 4 cave to the block 5 cave.
Methods have been tried, but today, sublevel caving is the only one used.One of the key factors affecting the mining costs in sublevel caving is the amount of development work for production.This cost is very dependent of the sublevel height.As the sublevel height increases, the amount of development work necessary for production decreases.
