21/04/2013  Introduction - Sublevel caving is usually carried out when mining of the orebody through an open pit method is no longer economically feasible. Mining now proceeds underground, underneath the open pit. At first, both a raise and a network of tunnels are made. At different sublevels, jumbos are used for long hole drilling, drilling directly upwards into the roof.

Sublevel caving - ScienceDirect

Underground mining in Sweden produces annually about 40 million tonnes of ore and rock, the principal mining systems being sublevel caving, sublevel stoping, block caving, open stopes and pillars, and shrinkage stoping. As far as quantity is concerned, sublevel caving is now the most important method with about 25 million tonnes per annum out of which Kiruna alone accounts for 19 million ...

Sublevel Caving - Oraee

Caving Mining Methods. Generally, caving methods extract ore, using the principle of fracturing the ore body and the rocks around it, inducing breaks in the whole strata and hence drawing the manageable ore, under more or less controlled conditions. There should therefore be no drilling and blasting, cutting or ploughing required. Sublevel Caving. In this method, the stope is divided into ...

When applying sub-level caving method to the mining of steeply dipping narrow veins (par-ticularly stock worked narrow veins with poorly defined host rock contacts), the flow of ore can be assumed similar to granular material flow that is not only constrained by the end walls, but also affected by the hangingwall and footwall (a confined flow) [2–7]. Under inclined boundary constrained ...

The sublevel caving (SLC) mining method has evolved over the last 100 years. The method was first used in the early 1900s in soft iron ore mines in Minnesota and Michigan, USA (Hartman and Mutmansky, 2002) . It represented an evolution from top slicing, but was initially highly labour intensive and required heavy timber support (Hartman and Mutmansky, 2002). Only part of the ore was blasted ...

Caving Mining Method Classification and Characteristics

Sublevel caving method is mainly used in the mining of iron ore deposits, most of which are newly built mines. At each stage, the surrounding rock should be artificially caved to form overburden rock. This mining method has the advantages of high strength, high efficiency, low cost, simple process, high mechanization degree, and safe production.

15/06/2018  Sublevel caving is a method often evaluated in parallel with block and/or panel caving options. It requires multiple levels of development and ongoing ring blasting for production. Sublevel caving allows for a more selective extraction but typically achieves lower production rates than block and panel caving methods.

Definition of sublevel stoping - Mindat.org

A mining method involving overhand, underhand, and shrinkage stoping. Its characteristic feature is the use of sublevels. The sublevels are worked simultaneously, the lowest on a given block being farthest advanced and the subs above following one another at short intervals. The uppermost sublevel underneath the cover is partly caved.
