Jul 25, 2018· 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.
Copper and diamonds are the predominant commodities currently being mined by block caving. Shown here is a scan, developed using Geovia’s PCBC software, of the bottom of a kimberlite pipe at the Finsch diamond mine, displaying selected draw points and draw cones.
In the block-caving mining method, the orebody is undercut so the base of the orebody starts collapsing, or caving, due to the mass of overlying material. “The orebody subsides under gravity, gathering at draw points for collection and, later, processing.

Jun 15, 2018· Despite the long lead time required ahead of an investment decision and the high capital investment required to establish a caving mine, the current cave mining techniques of block, panel and sublevel caving are presently the only viable underground mining methods that can be used to extract large, deep, lower-grade ore deposits in harsh geological and geotechnical environments.
Block caving mining sequence 1.Mining begins by developing access to the orebody, ventilation raises and the like 2.When access is deep enough a drift is extended towards the orebody and is then developed so that it circles the orebody. Several other drifts are developed for workers and equipment.
Caving mining method is a mining method that realizes ground pressure management by caving surrounding rock. That is, with the progress of the stoping work, fill the goaf with forced or natural caving surrounding rock to realize ground pressure management. This article will introduce the classification and characteristics of caving mining

Dec 12, 2018· 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.

Cave Mining 2040 aims to develop solutions that reduce lead times and capital investment by transforming cave mining as it’s presently practised to methods that improve its viability, safety, cost, production, and profitability; while improving its societal and environmental acceptance.
The Cadia and Ridgeway goldmines of Newcrest Mining in western New South Wales are examples of successful block caving. Done well, block caving is a cost-effective way of extracting large volumes of ore in an underground setting. But, like many advances in science and technology a better understanding of block caving started in a trial and
Drill and blast mining methods permit a degree of flexibility during the course of mining and allow for changes in techniques with technical improvements in equipment and blasting techniques. Block cave mining allows very little freedom in change once the layout in
stoping, cut-and-fill, longwall mining, sublevel caving, and block caving. The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers. 1.

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.

The term 'block caving' is used for all types of gravity caving methods. There are three major systems of block caving, and they are differentiated by the type of production equipment used. (1) The first system based on the original block cave system is the grizzly or gravity system and is a full gravity system wherein the ore from the
Drill and blast mining methods permit a degree of flexibility during the course of mining and allow for changes in techniques with technical improvements in equipment and blasting techniques. Block cave mining allows very little freedom in change once the layout in complete or virtually once the design has been approved.
Bulk mining methods . 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 rock to fall into.
Block caving is being looked to as one method of bulk mining to access these ores, as it is recognised as one of the most economic underground mass mining methods to
