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.

Sublevel 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 5mx3.7m sublevel nature of drifts aids in the safety of this mining method.

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, panel caving offers low operating costs, and lower development costs due to its progressive approach. SuB-LeVeL CAVING Sub-level 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.

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.
