Block caving is employed principally for mining low-grade ores where the inevitable loss of some ore and some dilution with capping and wall rock are permissible and where mining must be done on a large scale and at a lower cost than can be obtained by the use of supported-stope or other selective mining …

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.
Mining techniques can be divided into two common excavation types: surface mining and sub-surface (underground) mining. Today, surface mining is much more common, and produces, for example, 85% of minerals (excluding petroleum and natural gas) in the United States, including 98% of metallic ores.
Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades. Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material, 2) the slusher system for coarser material and 3) the ...
cost of mining equipment for sub level caving mining. The unique Wassara hammer was initially developed for sub level caving and can easily increase the length of blast holes way beyond 60 meters. Scaled up production with longer blast holes The LKAB mining company owns the two largest iron ore underground mines in the world.

Sub-level caving is an advanced and highly efficient low-cost 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 sub-evels spaced at regular intervals throughout the deposit.
The cost of sorting 1 ton of $68.64 ore from the run-of-mine product is $1.95. Expressed in another way, the sorting cost per ton of run-of-mine ore is 1.95/6.51 or $0.30. The cost of mining 1 ton of run-of-mine ore is $2.34. The cost of transporting ore from the mine to the mill on contract is $1 per ton.

Cost Minimization. In general sublevel stoping is a high production, yet low-cost 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.
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.

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 large-scale mining methods such as sub-level caving.
Sub-level caving Summary: The proposed mining method was dismissed as being impractical as a result of geotechnical and brow wear concerns, and it was suggested that an 'incline cave' mining concept be investigated.
Due to caving of waste rock into the blasted ore, a certain degree of ore loss and waste rock dilution comes with the method. Caving will, sooner or later, also cause subsidence on the surface. Sublevel Caving is a productive large scale mining method that enables safe and efficient use of mining equipment.
possible. Historical data at Shabanie mine, a Zimbabwean sub-level caving underground mining operation, confirms this practice. However, the high cost of underground development means that the luxury of large buffer mineral reserves cannot be justified. Furthermore significant increases in the costs …
