Sublevel Caving Technique | Mining | Drilling Rig

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.

Sublevel Caving - Oraee

Caving Mining Methods. Generally, caving methods extract ore, using the principle of fracturing the ore body and the rocks around it, inducing breaks in the whole strata and hence drawing the manageable ore, under more or less controlled conditions. There should therefore be no drilling and blasting, cutting or ploughing required. Sublevel Caving. In this method, the stope is divided into ...

Sublevel caving: Engineered to Perform - Elexon Mining

02/10/2013· 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. In addition to a low unit cost, sub-level caving …

Production Scheduling in Sublevel Caving Method with …

Sublevel caving is one of the main underground mining methods for hard rock mining and there are limited studies about its long-term production scheduling. In this paper, an integer linear programming (IP) model with the objective of net present value (NPV) maximization is developed for production scheduling that is suited for sublevel caving method. The model contains acceptable technical and ...

Sub-level open stoping - QueensMineDesignWiki

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. In general this method is fairly safe as the mining tends to retreat away from previously ...

09/03/2018· As compared to other mining methods, sublevel caving allows for a quicker and less expensive mining process. However, sublevel caving leads to greater dilution and is therefore used for lower ore bodies. The costs for sublevel caving range from $5-8$/tonne. Block Caving. Block caving is the logical step-up of sublevel caving. As with sublevel caving, the ore is mined as one large stope, …

Sublevel caving - ScienceDirect

Underground mining in Sweden produces annually about 40 million tonnes of ore and rock, the principal mining systems being sublevel caving, sublevel stoping, block caving, open stopes and pillars, and shrinkage stoping. As far as quantity is concerned, sublevel caving is now the most important method with about 25 million tonnes per annum out of which Kiruna alone accounts for 19 million ...

Definition of sublevel stoping

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. The caved cover follows down upon the caved ore. The broken ...

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. This talk will review some of the recent developments in SLC mining and poor design practices to avoid.
