Block Caving Production And Mass Mining

Block caving: A new mining method arises | Geoengineer.org

Jul 25, 2018 · 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.

Block Caving - Ground Truth Trekking

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 - Production and Mass Mining - MDA

Underground mass mining methods present several geotechnical challenges and risks inherent with block cave mining environments. Underground mining methods such as block, panel, and sub-level caving continue to be the primary choice for deeply situated massive orebodies, due to the high production rates and low operating costs involved.

Block Caving Mining Method 101 - Newtrax Technologies Inc.

Block Caving . Block caving is large-scale mining method that allows for huge volumes of rock to be extracted efficiently. However, the development time before production starts is longer compared to other mining methods. By drawing rock from the extraction level in the lower part of the mine, a gap is created.

Dec 01, 2018 · In the right conditions, the advantages of block caving make it an alternative that is now being considered more often. Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower- …

(PDF) Block caving - ResearchGate

Mining costs, including all direct, indirect and fixed costs, except royalty and lease payments, ranged from $1.04 per ton for chamber and pillar to $1.35 per ton for block caving, using LHDs.

Predicting the Block Caving Behavior of Orebodies

Block caving is an efficient mass-production method for the underground mining of large orebodies. However, the block-caving method requires a substantial investment in developmental works, based on the assumption that the rock will cave. Efficient block caving is prevented if the rock forms stable arches or breaks into fragments that are too large to pass easily through the …

mining and mines: Block Caving

Ore properties: A typical ore body should have a fairly large lateral extent with well distributed mineralization, with fairly weak or fairly strong rock with enough fractures in different orientations to allow the rock mass to break into small pieces under gravity to pass through the draw holes into the production drifts.The horizontal area of the mining block being mined is usually …

Mass Mining Diamonds | SRK Consulting

Mass mining including block caving, incline caving, front caving, sub-level caving and sub-level retreat are the principal mining methods for primary diamond deposits worldwide. Diamonds have only been mined on an industrial scale within the past 150 years, mainly as open pit mines.

Block Caving – A Viable Alternative? | Golder

Jul 10, 2018 · In the right conditions, the advantages of block caving make it an alternative that is now being considered more often, such as at Seabridge’s KSM Project. 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.

Block Caving Cu-Au Porphyry - SRK

Cave Mining Cu-Au Porphyry. There are over 45 cave mining projects in various stages of studies and development around the world. Cave mining methods will be the underground method of choice in the future. It is only relatively recent that this mass mining method, despite 70 years of use, has begun proving its potential.

Resolution Copper Mining Method - YouTube

Nov 08, 2012 · Resolution Copper will use the panel caving mining method, a variation of block caving to break up the underground ore. This technique uses gravity primarily to break the rock. Panel caving is ...

Underground mining (hard rock) - Wikipedia

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as …

Keeping up with caving - Redpath Mining

46 BLOCK CAVING Keeping up with caving Caving mining techniques are experiencing a surge of interest, thanks to a combination ... Upward caving of the rock mass is induced by under-cutting the block and blasting it. This ... attainable through block or panel caving. Production rates achieved in sub-level

Block caving reaches deeper deposits at KSM | Golder

The vertical nature of the deposits allows for block cave production with high ore columns and low dilution. Golder helped determine that block caving could be done with an operating cost similar to that of the open pit as it deepens. Just as importantly, block caving would be able to deliver the volumes of ore comparable to open pit mining.
