Sublevel caving: Engineered to PerformOct 02, 2013 · 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 caving.
Digging deeper: Mining methods explained | Anglo Americansublevelcaving, where levels of the ore are blasted by explosives; and block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity. We use these three different types of underground mining techniques for coal, diamonds and copper.

Block caving mining method with Elfen software, explained ...Caving is the lowest cost underground mining method for large nearvertical orebodies provided that the drawpoint size and the handling facilities are tailored to suit the caved material. The economic viability of a block cave and its productivity levels are dependent upon the degree of primary fragmentation that occurs within the seismogenic zone.

Simon Steffen of Elexon Mining discusses methods for optimising production at modern sublevel caves, while maximising ore grades and recovery. Sublevel caving is a highly efficient, topdown, underground bulk mining method.
miningmining mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on .

PercussiveSublevel Caving. Used for near surface large tonnage operations that require little development. Higher initial cost but much lower operational costs during production with multiple mucking points. Typically utilizes top hammer drilling such as the Stopemaster, Solo, or small diameter Cubex drills.
Study on the Rock Mass Caving and Surface Subsidence ...Due to the influence of geological conditions, orebody distribution characteristics, and mining technology, most of these underground iron mines are mined by the sublevel caving method [1–3], which is characterized by extraction on a large scale and high production efficiency with low mining cost. However, sublevel caving mining inevitably ...

(PDF) An assessment of dilution in sublevel caving at ...1 Problem definition The sublevel caving areas at Kazansi Mine currently contribute about 30% of the total ore produced in the mine. However, the rising dilution levels in the sublevel caving areas has led to drops in the grade of the ore, increase in mining and processing costs and also reduction in the profit margins of the mine.
Sublevel cavingSublevel Caving Safety. Sublevel caving is a relatively safe mining method since the operations take place in small areas at a time and are highly mechanized. The uniformly distributed nature of generally sublevel nature of drifts aids in the safety of this mining method.
