Sublevel caving: Engineered to Perform - Elexon Mining

Oct 02, 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.

Introducing Footprint Finder for Sub-Level Caving ...

Dec 18, 2017 · For decades, mining companies have trusted GEOVA PCBC's footprint finder application to quickly and effectively evaluate the footprint of block cave operations. Now PCSLC (for sub-level caving) has its own tool to rapidly evaluate sub-level cave scenarios to determine which option will be most attractive and robust.

Sub-level caving success at Syama - Mining Magazine

Unlike other bottom-up caving methods (block cave, panel cave) sub-level cave mining is a top-down method and therefore does not require large initial investments in mining infrastructure prior to commencement. The Syama sub-level cave commenced on the 1105 level .

Sublevel caving - ScienceDirect

The question whether sublevel caving is practicable even at greater depths below ground level has often been discussed. Both theoretical and practical points of view indicate a positive answer. A few Swedish metalliferous mines operate sublevel caving already today at depths of over 700 m below ground level.

Sub-level open stoping - QueensMineDesignWiki

This method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent. The production for a mine using sublevel stoping can range from 15- 40 tons/employee-shift, while one stope can produce greater than 25000 tons per month.

Sub Level Caving - Rana Gruber

Sub level caving method allows working in parallel on different sub levels in the mine. This means that continuous excavation works can be on-going at one sub level without interfering with another. Project Sublevel Caving was carried out during the years 2009 and 2011, with a budget on 450 million NOK.

Sub Level Caving Free Essays - PhDessay

7. 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.

FOURTH INTERNATIONAL SYMPOSIUM ON BLOCK AND .

ON BLOCK AND SUBLEVEL CAVING BACKGROUND The growing popularity of caving methods around the world is largely due to the very low production cost and the intrinsic safety associated with the mining approach. It is often the only viable mining method for some of the lower grade massive orebodies that are becoming too deep for open pit mining.
