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 ...

Mar 15, 2017· Mining giant Rio Tinto is currently reviewing a possible investment in block caving at the Argyle Diamond Mine in Western Australia. High costs and low prices have hurt diamond miners in recent years and the company must decide is the substantial initial investment in a block cave will pay off.

The mine consists of two ore zones, East and West, and mining of these zones is currently conducted using the sublevel caving method. When mining commenced in the Western zone, the span was insufficient to induce caving of the country rock above.

the mine reverted to mechanized block caving in 1989, a method that is still being used. 5. Mechanised block cave mining Block caving is generally considered the lowest cost underground mining method with mining costs approaching those of open pits once the high capital costs of installin.g the required mining infrastructure has been spent.

Cave mining techniques are the most popular methods for exploiting massive orebodies deep within the earth. ... Specific examples of cave mining techniques include block caving, panel caving, inclined-drawpoint caving, cut and fill mining, shrinkage stopping, sublevel longhole mining, room-and-pillar mining and front caving.

Keeping up with caving

Mining - Mining - Blasthole stoping: When the dip of a deposit is steep (greater than about 55°), ore and waste strong, ore boundaries regular, and the deposit relatively thick, a system called blasthole stoping is used. A drift is driven along the bottom of the ore body, and this is eventually enlarged into the shape of a trough. At the end of the trough, a raise is driven to the drilling ...

Abstract: LKAB has been mining iron ore with the sublevel caving mining method in northern Sweden for more than 60 years. Throughout the years, LKAB has improved this mining method to stay competitive in a tough international iron ore market. Improvements in drilling and blasting technology have helped LKAB increase the scale of sublevel caving and therefore decrease its mining costs in ...

Rock Blasting in Underground Mining

Three principal underground mining methods: open benching, sublevel caving and incline cave mining were implemented at the Ekati mine. Diavik Diamond Mine started open pit production in 2003. By 2005, underground development had commenced with plans to mine the …

Sub Level Caving Method (block caving)

Just as importantly, block caving would be able to deliver the volumes of ore comparable to open pit mining. This meant that the mill, set up to process ore from the open pits, would continue to operate at its usual efficiency when fed by the block cave mines. One problem Golder addressed is the strength of the rock within the ore body.

Jul 25, 2018· 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 that fills with its own rubble as it collapses.
