Get PriceThe most viable way to recover the ore body is by a well established underground mining method called block caving Block caving is safe environmentally sound and cost effective for mining a large deep orebody In block caving a large section of ore is initially undercut by drilling and blasting causing it to collapse under its weight

Get PriceThis method can be used for other new mines and can also be extended in the open pits operations This is the reason that block mining is referred to as an underground open pit mining version Block caving will come with financial and technical challenges Though the block caving comes with many benefits and advantages at the same time it also
Get PriceThat method called block caving is being proposed as an option to economically extract deeper mineral deposits or those located in challenging terrain less amenable to open pit mining Seabridge Gold has several prospective gold copper porphyry deposits in northern British Columbia Canada collectively known as the Kerr Sulphurets Mitchell KSM property
Get PriceSep 2 2021Block cave mining operating costs are typically in the order of one tenth of what other underground mining methods cost largely driven by economies of scale where production rates can reach 30 000 to 100 000 tonnes per day In addition drilling and blasting costs are far less and there are no backfilling costs
Get PriceMar 7 2022Mining engineer David Sprott has stated that block cave mining is the only underground mining method that can provide comparable open pit production rates and operating costs Block caving is used around the world in Canada USA Australia Chile Indonesia Mongolia South Africa and Zimbabwe

Get PriceJul 7 2022There are four main mining methods underground open surface pit placer and in situ mining Underground mines are more expensive and are often used to reach deeper deposits Surface mines are typically used for more shallow and less valuable deposits What are the underground mining methods
Get PriceMay 28 2022Sub level caving also allows for a slightly more selective extraction of the orebody than is attainable through block or panel caving Production rates achieved in sub level caving operations are typically lower than for block caves but higher than for stoping methods Caving is a non selective bulk mining method
Get PriceBlock caving is a mining method that relies upon natural forces to break the rock The cave is initiated by an undercut where a large area beneath the mining block is removed; gravity induced stresses then develop within the rock causing it to fracture The fracturing process is progressive and affects the entire rock mass overlying the undercut
Get PriceThis method is based on the assumption that ore fractures and breaks by itself due to the presence of internal stresses and forces caused by the weight of the ore body and also the downward movement of the broken rocks 1 The deposit is divided into large blocks usually square in shape Each block is undercut completely by a horizontal slot

Get PriceSublevel Caving is one of the most advanced mining methods This method is usually undertaken when mining the orebody through an open pit is no longer economically viable In Sublevel Caving mining starts at the top of the orebody and develops downwards Ore is mined from sublevels spaced at regular intervals throughout the deposit

Get PriceThe mine has moved and milled as many as 22 000 tonnes of ore in a single day and routinely extracts 18 500 from Canada s only block cave Like other prolific block caves New Afton enjoys enviable efficiency at extremely low operating costs But the mine has also had to conquer one of the biggest block cave challenges mud rush
Get PriceProduction rates achieved in sub level caving operations are typically lower than for block caves but higher than for stoping methods Caving is a non selective bulk mining method What is panel caving In mining Mining massive deposits …for such deposits is called panel/block caving It is used under the following conditions 1 large
Get PriceThe 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

Get PriceBlock 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
Get PricePanel or block caving is widely considered the new frontier as mining operations naturally head underground The method involves massive volumes of material and large investment Taking a strategic approach CaveLogic targets the most cost effective underground mining method in a transparent analytical way Analyse multiple scenarios
