ON BLOCK AND SUBLEVEL CAVING BACKGROUND The growing popularity of caving methods around the world is largely due to the very low production cost and the intrinsic safety associated with the mining approach It is often the only viable mining method for some of the lower grade massive orebodies that are becoming too deep for open pit mining

stoping, cut and fill, longwall mining, sublevel caving, and block caving The second section describes underground mining equipment, with particular focus on excavation machinery such as boomheaders, coal cutters, continuous miners and shearers 1 Underground Mining Methods 1 1 Classification of Underground Mining Methods

Caving Methods of Mining There are three distinctive methods of working large deposits that involve, in some way, the factor of caving Slightly different names are in use, but those that are simple as well as descriptive are top slicing, sublevel caving, and block caving

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 Subsidence reaches surface at the Ridgeway underground mine Using this method, mining is planned to extract rock from the stopes without filling the voids this allows the wall rocks to cave in to the extracted stope after all the ore has been removed

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight It is the underground version of open pit mining In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses

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

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

Oct 02, 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

Long hole stoping as the name suggests uses holes drilled by a production drill to a predetermined pattern as designed by a Mining Engineer Long hole stoping is a highly selective and productive method of mining and can cater for varying ore thicknesses and dips 0 90 degree

Apr 08, 2016 The industry perception is that sublevel caving is a dirty mining method i e high dilution and low recovery However, there were several successful sublevel cave mines executed in the past The success of a sublevel cave mine is not by chance they are engineered to perform

Specific examples of cave mining techniques include block caving, panel caving, inclined drawpoint caving, cut and fill mining, shrinkage stopping, sublevel longhole mining, room and pillar mining and front caving Cave mining is typically used to mine copper, copper gold, iron and molybdenum

Dec 01, 2016 Sublevel Caving Sublevel Caving is one of many different methods for underground hard rock mining It is a large scale mining method suitable for large ore bodies with a steep dip and a rock mass with a host rock in the hanging wall will fracture under controlled conditions

Apr 05, 2019 Sublevel caving is a large scale mining method, suitable for large ore bodies with a steep dip and a rock mass where the host rock in the hanging wall will fracture under controlled conditions

Long hole stoping as the name suggests uses holes drilled by a production drill to a predetermined pattern as designed by a Mining Engineer Long hole stoping is a highly selective and productive method of mining and can cater for varying ore thicknesses and dips 0 90 degree

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

Fan drilling is where holes are drilled fanning out from the roof of the sublevel The diagram to the right shows the pattern as it would be applied to sublevel mining Fan drilling is mostly seen in sublevel caving, however can be applied to stoping in narrow stopes as well

The wall caving is induced by mining the ore in controlled sequence, usually from hanging wall to footwall and from top to bottom Sublevel caving is often used in conjunction with surface mining Sublevel caving extracts the ore via sublevels, which are

Unlike other bottom up caving methods block cave, panel cave sub level cave mining is a top down method and therefore does not require large initial investments in mining infrastructure prior to commencement The Syama sub level cave commenced on

A preliminary economic assessment PEA has selected a combination of sublevel caving and mechanized cut and fill as the mining methods, with a ramp serving as the primary mine access

Block gravity caving is a bulk underground mining method, which allows large low grade deposits to be mined underground This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted It is a useful technique to extend

Sublevel Caving Sublevel Caving is one of many different methods for underground hard rock mining It is a large scale mining method suitable for large ore bodies with a steep dip and a rock mass with a host rock in the hanging wall will fracture under controlled conditions

The objective of all mining is to obtain the highest possible ore recovery with as little waste rock dilution as possible and at lowest possible cost Sublevel caving has great potential possibilities, but unfortunately it is often not recognized that this method requires very careful planning and control

Sublevel Stoping Underground Mining Methods in sublevels production when using sublevel caving na base level or ore body, when it is used block caving, sublevel stoping and VCR

Thank you to all who attended the Caving 2018 Symposium The papers from the Fourth International Symposium on Block and Sublevel Caving are freely downloadable on the ACGs Online Repository The ACG thanks open access sponsor OZ Minerals for their support

An overview of a wireless blasting system for use in sublevel caving operations that significantly reduces the risk posed to mine workers Sublevel cave SLC mining is breaking ore bearing rock through blasting and drawing it out under the waste rock that is caving into the void created SLC mines

Apr 08, 2016 The industry perception is that sublevel caving is a dirty mining method i e high dilution and low recovery However, there were several successful sublevel cave mines executed in the past The success of a sublevel cave mine is not by chance they are engineered to perform

Block gravity caving is a bulk underground mining method, which allows large low grade deposits to be mined underground This method involves undermining the orebody to make it collapse under its own weight into a series of chambers from which the ore extracted It is a useful technique to extend

This characteristic interplay of forces can create suitable conditions for sublevel caving even at greater mining depths below ground level The formulae quoted above for the approximate calculation of the parameters of sublevel caving or front caving can be applied for mining descending from foot wall to hanging or vice versa

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

Forefront said the growing popularity of block caving and sublevel caving around the world is largely due to the very low production cost and the intrinsic safety associated with these mining methods They are often the only viable mining methods for some of the lower grade massive orebodies that are becoming too deep for open pit mining
