Jun 04, 2010 This video describes the block caving process with 3D animation. Block Caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated over the undercut. The drawbells serve as a place for caving

Inside block caving: the deep mining method of the future

Feb 14, 2020 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. According to Suorineni, “caving heights have also increased drastically from about 200m to 500m”, creating so-called ‘super caves’.“There is insufficient experience caving in these environments,” he adds, which is a

Block Caving groundtruthtrekking

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.

8.4.2a Block Caving ABC 123: Testing Site / Course

This method, which was developed in the U.S. after WW I, is well suited for mining in weak orebodies. Panels or blocks of ore are undercut. Once undercut, the weak orebody begins to cave under its own weight. The caved ore is drawn off through draw points.

Block caving method SlideShare

Jul 14, 2014 Block caving is the mining method in which masses, panels, or blocks of ore are undercut to induce caving, permitting the broken ore to be drawn off below. If the deposit is overlain by capping or bounded by drawing the ore. This method is unlike sublevel caving, in that both the ore and the rock are normally involved in the caving.

Underground Mining Methods — New Pacific Metals

Block Caving. Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

mining and mines: Block Caving

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 Underground Mining -Theory and Experiences

Jul 20, 2019 Block caving Block caving is group of mining methods that has been developed from the sublevel caving. As its name is saying, ore block is caved by influence of the gravity and drawn at its bottom. This group can be divided into conventional block caving and panel caving that is dominant.

Underground mining (hard rock) Wikipedia

Block caving is used to mine massive steeply dipping orebodies (typically low grade) with high friability. An undercut with haulage access is driven under the orebody, with "drawbells" excavated between the top of the haulage level and the bottom of the undercut. The drawbells serve as a place for caving

Block Caving A Viable Alternative? Golder

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 QueensMineDesignWiki

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

Block caving Canadian Mining Journal

Dec 01, 2018 Another key advantage to an underground mining method like block caving, as compared to open pit methods, is the large reduction in surface waste disposal needs. As open pits get deeper, their ratios of waste rock to ore often get higher and the waste must be placed in ever-increasing surface storage areas.

AngloGold Ashanti confirms caving plans in Colombia

Due to the caving constraints of the deposit, the first production level to initiate caving (undercut) is expected to be located around 100 m below the top of the mineralisation at 1,675 masl (circa-525 m below the top of the mountain), with the mining block extended around 550 m in depth (20 production levels at 27.5 m interlevel spacings).

Types of Mining Methods Sell Side Handbook

Mar 09, 2018 As compared to other mining methods, sublevel caving allows for a quicker and less expensive mining process. However, sublevel caving leads to greater dilution and is therefore used for lower ore bodies. The costs for sublevel caving range from $5-8$/tonne. Block Caving. Block caving is the logical step-up of sublevel caving.

Oct 04, 2012 Block caving is expected to extend the life of the Argyle mine "until at least 2019". The mine had been an open pit operation, before Rio Tinto decided to build an underground mine below the

A transition from a large open pit into a novel

Jun 01, 2019 The business case to continue with the mining of the Chuquicamata orebody is to change from the current large open pit to a novel macroblock variant block caving geometry. This requires a production rate of 140,000 t/d (50 Mt per annum), with a continuous material handling system to achieve the 7-year ramp-up to full production.
