Jul 25, 2018· Block caving is a new alternative method of developing new mines or extending the operation of open pits. 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.
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.
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.
Monitoring system for observations of rock mass deformations caused by sublevel caving mining system. After modifying the mining sequence at Turmalina, while maintaining the sublevel stoping mining method, dilution has diminished significantly and run …
This method is usually considered as an alternate to sublevel caving when a lower dilution method is needed and where the rock is fairly competent. The production for a mine using sublevel stoping can range from 15- 40 tons/employee-shift, while one stope can produce greater than 25000 tons per month.

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 …
Sublevel caving is a large-scale mining method, suitable for large ore bodies with a steep dip. The setup is similar to long-hole stoping except loft raises are not required. Also, mining starts at the top of the ore body and progresses downwards in a safe sequence.
Block Caving . Block caving is large-scale mining method that allows for huge volumes of rock to be extracted efficiently. However, the development time before production starts is longer compared to other mining methods. By drawing rock from the extraction level …
Block Caving. Block caving is essentially the underground version of open-pit mining. It’s the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
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.
Sub-level caving also allows for a slightly more selective extraction of the orebody than is attainable through block or panel caving. Production rates achieved in sub-level caving operations are typically lower than for block caves but higher than for stoping methods.” CAVING requIremeNts Caving is a non-selective, bulk mining method.
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.

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.
The cave mining method is proposed for Finsch Block 5 by detailing the findings of modelling and design work. There are three mining methods which are the most applicable to the Finsch Block 5 orebody:-Sublevel caving (SLC)-Block caving (BC)-Front caving (FC).
Stull stoping is a form of stoping used in hardrock mining that uses systematic or random timbering ("stulls") placed between the foot and hanging wall of the vein. The method requires that the hanging wall and often the footwall be of competent rock as the stulls provide the only artificial support.

Jun 14, 2019· There are several variants of the sublevel caving mining method among which variant applied in Kiruna mine in Sweden is best known. This mining method can be applied to numerous types of ore bodies with inclination from horizontal to vertical. If ore body is narrow its inclination should be steep in order to apply the method.

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.
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.
