Oct 02, 2013 Source Mining Magazine, September 2013. Sub-level caving is a highly efficient, top-down, underground bulk mining method. Recent developments in sub-level cave mining have advanced the understanding of the technique and its production performance, which allow it to now be considered as a highly viable alternative to open stoping and, in some cases, even to block caving.
Mar 03, 2017 Experience from LKAB, Sweden - Sub-level caving SLC is an important mass mining method, used at LKAB. The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses.

and 4.7 m sub-level caving height, approxi-mately 7.5 m thick coal is produced2. By using the sub-level caving method, some savings are obtained in development drift costs. However, during the caving operation coal losses and dilutions inevitably occur. The sum of coal losses amounts to approximately 20. The aim of this study is to find ways to
Caving Mining Methods Generally, caving methods extract ore, using the principle of fracturing the ore body and the rocks around it, inducing breaks in the whole strata and hence drawing the manageable ore, under more or less controlled conditions.
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.
The mining study considered sub-level caving SLC, a combination of SLC and sub-level open stoping SLOS and block caving mining methods. Previous studies considered open pit mining and SLOS. SLC was selected as the preferred and most suitable mining method for the project. The factors influencing the mining method selection were
Specific examples of cave mining techniques include block caving, panel caving, inclined-drawpoint caving, cut and fill mining, shrinkage stopping, sublevel longhole mining, room-and-pillar mining and front caving. Cave mining is typically used to mine copper, copper-gold, iron and molybdenum. It can also be used in the extraction of kimberlite ...

3 New sublevel caving layouts for mining at depth As discussed previously in this paper, it is expected that the current sublevel caving mining layout used at LKAB underground mines will not work properly at greater depths when mining under the current main level.
Costs of mining and other industrial operations have been found historically to fit this equation form. This is also consistent with the format of CES cost equations and the simplified models I
Caving methods are defined as those associated w ith induced, controlled, massive caving of the ore body, the overlying rock, or both. Th e exploitation workings in caving methods are designed to collapse, with intentional caving of the ore andor host rock. The three major caving methods are Longwall mining Sublevel caving

The caved rock or debris at the SLC interface reduces the fragmentation and the swelling of the blasted ring and it dissipates the explosive energy. These phenomena may immobilize the blasted ring, causing ore losses.
Feb 22, 2019 Caving methods compared with other underground mining methods are low-cost methods and have high production rates. Sublevel caving is one of the main underground mining methods for hard rock mining and there are limited studies about its long-term production scheduling.
A 4 million tonnes per annum Mtpa sub-level cave mining operation with an average copper equivalent grade of 2.31 in ore milled. A conventional copper concentration processing plant producing an estimated average of 66,000 tonnes of copper and 82,000 ounces of gold per annum for the first three years of full production.
Malmbergets mining methods. Large-scale sub-level caving is the method of mining. Production drilling at the access level is undertaken by five electric-powered automated rigs, with each rig drilling approximately 10,000 meters 33,000 feet of 11.5-centimeter 4.5-inch diameter holes per month.

Apr 05, 2017 Sublevel caving lacks the flexibility of supported-stope methods but is more flexible than block caving. The sublevel development serves to explore the ore body at each caving horizon before mining begins, and irregular boundaries can be followed more easily than with block caving and with less dilution from the walls.

Forefront said the growing popularity of block caving and sublevel caving around the world is largely due to the very low production cost and the intrinsic safety associated with these mining methods. They are often the only viable mining methods for some of the lower-grade massive orebodies that are becoming too deep for open-pit mining.
As mining progresses downward, each new level is caved into the mine openings, with the ore materials being recovered while the rock remains behind. Block caving is a large-scale or bulk mining method that is highly productive, low in cost, and used primarily on
Mar 16, 2017 Back Caving into Chutes. There is another principle that should be mentioned under mining methods. It is called back caving into chutes or chute caving and in some ways resembles block caving. The description of a mine employing this principle is given in Mining Without Timber, by Brinsmade, p. 181.
