Sub Level Caving Free Essays PhDessay
Sublevel caving techniqueSimplicity and low cost are the essence controlled drilling and blasting. Sublevel caving is in many respects simple. It can be used in orebodies with very different properties and it is easy to mechanize. In sublevel caving, ore is developed from a series of sublevels spaced at regular intervals throughout the orebody.

Sublevel caving techniqueSimplicity and low cost are the essence * Finally, most rock materials upon being blasted would like to bulk (swell) of the order of 50%. * In sublevel caving, it is the sublevel drift loed at the bottom end of the fan which is the primary provider of swell space for the ore in the ring.

Sublevel caving: Engineered to Perform Elexon Mining
Source: Mining Magazine, September 2013 Sublevel caving is a highly efficient, topdown, underground bulk mining method. Recent developments in sublevel 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 []
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 indie a positive answer. A few Swedish metalliferous mines operate sublevel caving already today at depths of over 700 m below ground level.

Cave Mining Techniques AZoMining
The removal of the ore causes a large gap or 'cave' where the orebody previously resided. Specific examples of cave mining techniques include block caving, panel caving, inclineddrawpoint caving, cut and fill mining, shrinkage stopping, sublevel longhole mining, roomandpillar mining and front caving.
