Block caving is a large-scale underground mining method relevant to the removal of low-grade, substantial ore physiques. With the quantity of literature on block caving this article identifies the need to provide a simple understanding of the process.
The block-cave mining method is capital intensive and can cost anywhere between $2 and $10 billion. While that is comparable to the cost of starting an open-pit mining operation, block caving ...
Jul 10, 2018· Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight ...
In classification of underground mining methods, caving methods are regarded as high production methods. These techniques are usually very costly and need great preparation. However, the high production rate of these methods, make them cost-effective . The Block Caving method .
The incline cave mining method for use at Finsch Diamond Mine was first documented by Paucar and Mthombeni (2004) in a paper presented at MassMinn 2004. This paper aims to discuss the incline cave mining method as proposed for Finsch Block 5 by detailing the findings of modelling and design work.
Feb 06, 2018· 1. Introduction. Block caving is a nonselective underground mining method that extracts ore from the bottom of the orebody to the top. This is achieved by developing production levels below the orebody before the extraction is started as shown in Figure 1.Once all development is completed, the orebody is undercut by blasting a layer of ore (1 and 2 in Figure 1).
Jul 10, 2018· Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight ...
Dec 01, 2018· Block cave mining is the only underground method that can offer comparable open pit production rates and operating costs. For new developments, block cave mining offers the further advantage of a smaller surface footprint with significantly less waste disposal requirements.
Mass Mining Technology (MMT) recommended that Dr. Laubscher, Dr. Guest and Jarek Jakubec undertake this task. In 2017, the design book 'Guidelines on Caving Mining Methods' was published as a practical tool for cave mining by The University of Queensland. Pictured above: Jarek Jakubec and .
Block caving has emerged as a cost-effective method of mining large, low-grade mineral deposits. The role of block caving Although the caving mining system was initially used for shallow orebodies, it has recently been applied at depths of 2km underground.
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.
Block caving-A new mining method arises. Block caving is a new alternative method of developing new mines or extending the operation of open pits. 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.
Block Cave Mining Techniques. The most commonly used cave mining technique is block caving. Block caving is a large-scale mining method that is particularly useful for mining low-grade or disseminated ore bodies which are at too great a depth to be exploited through open-cast mining.

Feb 14, 2020· As block caving is the only underground method that can offer comparable open-pit production rates and operating costs, the technique is set for a strong future on the mining stage. AusProof is celebrating 25 years of business in Australia in 2019.
In underground mining, block caving is the only method with the costs comparable to surface mining methods, especially open pit mining. A switch from open pit mining to block caving mining could ...
Block cave mining involves undercutting the ore body and allowing it to break up or 'cave' under its own weight, removing the need for explosives or blasting. The technologically sophisticated underground operation at Argyle is the first block cave mine in Western .

Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades. Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material, 2) the slusher system for coarser material and 3) the ...

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. The technique is commonly used to extract low grade copper, copper-gold, iron and molybdenum ores although ...

Jul 14, 2014· 1. Block Caving Method Virendra Suryawanshi [email protected] 2. Introduction The one u/g mining method that has the potential to rival surface mining in output and cost is block caving. Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to ...
