The research problems were investigated at the Mining Department of the Royal Institute of Technology, Stockholm with the collaboration of various Swedish mining companies, especially LKAB Kiruna. ... model experiments and largescale tests concerned with sublevel caving problems.
Sublevel Caving Technique Free download as PDF File (.pdf) or read online for free. An underground mining method used in large, steeply dipping orebodies where the wall rock is of an incompetent nature. Parallel drives are developed in the ore on equally spaced levels. The ore is then drilled and blasted using longholes between levels, often in a circular or fan pattern, on retreat.

Jul 14, 2014· This method is unlike sublevel caving, in that both the ore and the rock are normally involved in the caving. As in sublevel caving, The caving proceeds in a columnar fashion to the surface. The result is massive subsidence, accompanied by the exceptionally high production rate and great areal extent characteristic of block caving.
The industry perception is that sublevel caving is a "dirty mining method" ( high dilution and low recovery). However, there were several successful sublevel cave mines executed in the past. The success of a sublevel .
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.
The method is flexible, has rapid effect and integrates advantages of a nonpillar sublevel caving method and a sublevel room stoping method, and a new process is provided for recycling mediumstable and mediumthick ore bodies.
Jun 25, 2010· 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 .
Oct 23, 2014· Caving Underground Mining Methods (longwall, Sublevel caving, Block caving) 1. This material is intended for use in lectures, presentations and as handouts to students, and is provided in Power point format so as to allow customization for the individual needs of course instructors.
An overview of a wireless blasting system for use in sublevel caving operations that significantly reduces the risk posed to mine workers. S ublevel cave (SLC) mining is breaking orebearing rock through blasting and drawing it out under the waste rock that is caving into the void created. SLC mines have the most intensive blasting process of all the mining methods, as generally one or two ...

The 1893 mining disaster at Dolcoath mine in Cornwall was caused by failure of the stulls holding up a huge weight of waste rock. Squareset stoping. Squareset stoping is a method relying on squareset timbering. Square set timbers are set into place as support and are then filled with cement. The cement commonly uses fine tailings.
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 surface that takes place as ore is removed. In the transverse sublevel caving system shown in the ...
Oct 15, 2019· Underground Mining Methods and Equipment is intended as both a course and a technical reference for an audience of engineers, operators, contractors, consultants, regulators, practising geoscientists and students in the mining sector. The course provides a comprehensive introduction and reference for those who require a solid grounding in selection, design and development of mining methods .
Schematic layout for sublevel caving (after Hamrin, 1982) DEFINITION: A mining method which is applicable to low grade near vertical metallic or nonmetallic deposits. Mining progresses downwards .
Jun 15, 2018· 7. Sublevel caving. 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.
Sublevel caving. This method owes the first part of its name to the fact that work is carried out on intermediate levels (that is, sublevels) between the main production levels. It follows the same basic principles as the block caving mining method, but the caves are smaller in size and not as long lasting.

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
