Inquiry Online Contact UsSublevel 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.
2 Other articles where Sublevel caving is discussed 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.
Method of underground mining sublevel caving on tamakaimoana ore, including the sinking of sublevel workings, layer-by-layer breaking of ore on potatah on tamakaimoana ore and partial release of ore after blasting each layer through the end sublevel generation, the simultaneous dosed ore transport horizon floor, characterized in that a partial .
The loss and dilution of ore by sublevel caving mining method is influenced by gravity flow principles of caved granular materials rocks. Gravity flow of broken rock muck in dipping narrow veins is complex. By combined use of dimensional analysis and similitude studies in physical modelling coupled with numerical simulation, this paper reports results of a study of gravity flow of muck in .
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.

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.
Block Cave Mining Techniques. The most commonly used cave mining technique is block caving. Block caving is a large-scale mining method that is particularly useful for mining low-grade or disseminated ore bodies which are at too great a depth to be exploited through open-cast mining. This mining technique gets its name from the layout of the .
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 tonsemployee-shift, while.

During the production process, the ores fall as the covering layer is caved and the fallen rocks fill the goaf, which enable the continuous stoping. The method is favored for low cost, high efficiency and large scale. At present, there are mainly sub-column sublevel caving method, sub-column sub-leveling method and natural caving method.

Sublevel Caving. In this method, the stope is divided into sublevels, fairly close to each other, normally with 8-15m vertical interval between each two adjacent ones. These sublevels are called sublevel drifts or production drifts. Production is carried out from the sublevel drifts by means of long holes above the end of the production drifts.
1. Introduction. The modern sublevel caving, possibly developed in the iron mines of Sweden Hustrulid and Kvapil, 2008, is a widely used mining method in metallic mines across the world.This method has many advantages regarding safety and mechanisation Janelid and Kvapil, 1966.Because mining operation is carried out only in drifts, the safety of this method is relatively good, compared .
Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals1 such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining .

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 developed in the orebody at regular vertical spacing.

2 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.
