1. Introduction. Sublevel caving (SLC) is a mass mining method based upon the utilisation of gravity flow of blasted ore and caved waste method functions on the principle that ore is fragmented by blasting, while the overlying host rock fractures and caves under the action of mine-induced stresses and caved waste from the overlying rock mass fills the void created by ore Cited by: The Evolution of Sublevel Caving at Trojan Mine, Bindura, Zimbabwe, J G Taylor 1. The Evolution of Sublevel Caving at Trojan Mine, Bindura, Zimbabwe J G Taylor1 and R Chinamatira2 ABSTRACT Several technical and economic factors have to be taken into consideration in developing an optimal mining method.

The design for sublevel cave operations has traditionally been related to the buk flow of so lids in bins or hoppers. Mining engineers would apply the flow behaviour of bulk so lids to their mine design whiie allowing for appropriate draw conditions and production schedules.

Almost 20% of the ore is mine during development * Sublevels are established generally at m vertical intervals and about m horizontal intervals The vertical interval. 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. This dissertation will explore the process followed in the design of a sub-level open stope (SLOS) by using examples of actual stopes scheduled to be in production between August and February The main objective is to give the reader an understanding into sub-level open stoping and the design process followed.

Abstract: With increasing mining depths and excavation volumes comes not only increased rock stresses and more difficult underground mining conditions, but also increased surface effects, in particular from cave mining.

• Allows for fine and alternate particle properties. Small scale calibration • Produces ellipsoidal approximations of draw similar to those seen in reality.
• Software has been calibrated against many operational mines. The ore body is divided into vertical intervals called sublevel intervals. The ore within each sublevel interval is drilled in a fan-shaped design at a constant horizontal distance along the production drift, called burden.
The ore is blasted, slice by slice from the hanging wall side to the footwall side in a retreating manner (Cokayne Author: Gurmeet Shekhar, Anna Gustafson, Anders Hersinger, Kristina Jonsson, Håkan Schunnesson.Sublevel Stoping (version 2) Australia Mining Consultants.
Sublevel Stoping (SLS) is often regarded as a mining method for steeply dipping deposits in competent rock. The method involves extracting the ore between the sublevels. The sublevele intervals varies from mine to mine.Block caving is an extreme case of sublevel caving in which instead of a back of ore 5 to 10 ft.
thick, one 50 ft. thick is undermined and allowed to cave. The method is illustrated in Fig. 7. After the bottom of the block, or panel, is cut up into pillars by drift’s and cross drifts, the pillars are robbed, and then the remaining stumps are.
