Following the evolution of the mine plan through a number of stages the ‘sublevel shrinkage SLS with continuous fill’ mining method was implemented in 2010 to extract the Mt Wright orebody The production front in this mining method is similar to a sublevel cave SLC operation however backfill is placed into the top of the production zone as opposed to requiring the overlying strata to cave
Sublevel Caving SLC was selected as the mining method for the underground portion of the deposit based on the amenable geometry of the deposit and because productivity and cost advantages of SLC enable greater exploitation of the underground resource at greater margin than more selective mining methods Atlantic Nickel said
Jun 14 2019 · Ore is blasted from the sublevel drifts using explosive charges in fan pattern drilled upwards while loading is performed using underground loaders If ore body is thick sublevel drifts are placed perpendicularly strike of the ore body in chess pattern but if narrow ore body is excavated sublevel drifts are located along the strike
In mining Sublevel caving This method owes the first part of its name to the fact that work is carried out on many intermediate levels that is sublevels between the main levels The second half of the name derives from the caving of the hanging wall and Read More
Touted as the deep mining method of the future block caving is an underground massmining method that allows for the bulk extraction of large relatively lowergrade ore deposits that are vertical in orientation The method is an attractive alternative when planning to develop a new mine or to extend the life of an open pit operation
slice Mining continues upwards towards the surface until the ore body is depleted Sublevel Caving Sublevel caving is usually carried out when mining of the ore body 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
The three major caving methods are • Longwall mining • Sublevel caving • Block caving Longwall mining is used in horizontal tabular deposits mainly coal while the others have applications in inclined or vertical massive deposits a lmost exclusively metallic or nonmetallic
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 raiseand a network of tunnelsare made At different sublevels jumbos are used for long hole drilling drilling directly upwards into the roof

Sublevel caving SLC is a mass mining method based upon the utilisation of gravity flow of blasted ore and caved waste rock 1 The method functions on the principle that ore is fragmented by blasting while the overlying host rock fractures and caves under the action of

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
Jun 15 2018 · 7 Sublevel caving Sublevel caving is a method often evaluated in parallel with block andor 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
slice Mining continues upwards towards the surface until the ore body is depleted Sublevel Caving Sublevel caving is usually carried out when mining of the ore body 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
Mar 09 2018 · As compared to other mining methods sublevel caving allows for a quicker and less expensive mining process However sublevel caving leads to greater dilution and is therefore used for lower ore bodies The costs for sublevel caving range from 58tonne Block Caving Block caving is the logical stepup of sublevel caving
Abstract LKAB has been mining iron ore with the sublevel caving mining method in northern Sweden for more than 60 years Throughout the years LKAB has improved this mining method to stay competitive in a tough international iron ore market Improvements in drilling and blasting technology have helped LKAB increase the scale of sublevel caving and therefore decrease its mining costs in
Caving methods are defined as those associated w ith induced controlled massive caving of the ore body the overlying rock or both Th e exploitation workings in caving methods are designed to collapse with intentional caving of the ore andor host rock The three major caving methods are • Longwall mining • Sublevel caving
Sublevel Caving 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
Caving methods Caving methods include block caving sublevel caving and longwall emphasis allow me to repeat what I said earlier caving methods are used in settings where the ore or the host rock is so weak that it cannot support its own weight for any period of time the methods only work if the rock or the ore will readily cave under its own weight
Special issue on block and sublevel caving Caving mining methods are not new This ultimate underground mass mining approach has been practiced around the world for more than a century It is true however that cave mining and more specifically block Cave mining methods rely on the natural properties of the rock mass and natural forces
The mining method optimization in subsea deep gold mines was studied First an index system for subsea mining method selection was established based on technical feasibility security status
When it comes to mining method 67 percent of the cases involve block caving with 16 percent using sublevel caving to adapt to the local topography andor orebody type Fig 1b The integrated use of two methods in tandem – block caving plus sublevel caving or block caving plus panel caving – is increasing to facilitate excavation as well
