Oct 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.

Cost Minimization. In general sublevel stoping is a high production, yet lowcost method. It is a very popular method chosen when open pit mining activities are no longer economical and mines move to underground operations. The key to cost minimization when using this method is mechanization.
With the increased volume of ore per drilled meter, the overall productivity is significantly increased. Also, the controlled amount of deviation leads to a more homogeneous fragmentation which increases the overall throughput of the whole mining process. This is particularly beneficial for largescale mining methods such as sublevel caving.

7. Experience from LKAB, Sweden – Sublevel 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.

mining, panel caving offers low operating costs, and lower development costs due to its progressive approach. SuBLeVeL CAVING Sublevel caving is sometimes used where large open pit mining operations transition to underground extraction methods, although it is often used for independent underground projects too.
Sublevel caving is an advanced and highly efficient lowcost bulk underground mining method that provides early access to ore. Mining commences at the top of the deposit and develops downwards. Ore is mined from subevels spaced at regular intervals throughout the deposit.
