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.

methods such as mining scale, production rate, selectivity, personal ingress requirements and extraction flexibility.-For the large, often low grade orebodies, selecting the proper mining method is difficult: block caving is generally preferred due to low labor requirement, and low cost per tonne.-Basic prerequisites to applying block caving method are that caving can be

Cave mining 2040: advancing cave mining to

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.

Sublevel Caving Mining Method

A method in mining by sublevel caving in which in a development phase are driven haulage drifts or shafts and from said drifts or shafts are driven cross-cuts in an orebody with a spacing vertically and horizontally suitable from an economical and technical point of view, from which cross-cuts one or more longitudinal drifts are driven in said .

Sub Level Caving PHDessay

Description of sublevel caving method 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.

Design of a new layout for sublevel caving at depth

LKAB has been mining iron ore with the sublevel caving mining method in northern Sweden for more than 60 years. Throughout the years, LKAB has improved this mining method to stay competitive in a tough international iron ore market. Improvements in drilling and blasting technology have helped LKAB increase the scale of sublevel caving and therefore decrease its mining costs in development

Cave Mining Today's Challenges SRK Consulting

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.

Method Selection A Numerical Approach

Although experience and engineering judgment still provide major input into the selection of a mining method, subtle differences in the characteristics of each deposit, which may affect the method chosen or the mine design, can usually be perceived only through analysis of measured characteristics.

An overview of block caving operation and available

Block caving technique is a mass mining method in which gravity is used in combinationwith internal rock stresses to fracture and break the rock mass into pieces that can be handled by miners. This method is normally applied to large, low-grade ore-bodies because of its low production cost and high capacity. In this paper, first, production scheduling methods for underground mining are

mining and mines: Block Caving

Block caving is an inexpensive bulk mining method where the ore is drawn by gravity and which is suitable for ore bodies which are low grade and are consistent in their grades. Depending on how the ore is broken there are three block caving systems 1) The Grizzly system for fine material, 2) the slusher system for coarser material and 3) the LHD system for very coarse material. Full gravity
