Block Caving Mining Method: Transformation and Its Potency in

The ﬁrst documented underground mine which applied the block caving method was the Pewabic iron mine in 1895 [43]. Although the block caving method has been known for over a decade, its massive deployment has only occurred in the last twenty years. During that time, the number of cave mining projects increased almost four times, Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight and Block Caving: A Viable Alternative?

Block Caving: A Viable Alternative? WSP

Block cave mining is an underground mass mining method that allows for the bulk extraction of large, relatively lower grade, ore deposits with substantial vertical dimension. In block caving, a large section of ore is initially undercut by drilling and blasting, creating a large unsupported roof that will start to collapse under its own weight and In this paper, first, production scheduling methods for underground mining are reviewed and then, block caving method is described. Afterwards, available mathematical models of block cave scheduling and their shortcomings are described. Finally, the conclusions and future work are presented. 1.

Make tunnels in the “corridors” you created in Step 2. The spacing is up to you, but for maximum efficiency, put them about six spaces apart. If you want to be thorough, put them two spaces apart. It will get all the ores for sure, but you might find that you’ve already collected all the ores from half of the tunnel.The block caving mining method has become increasingly popular in the last two decades.

A systems approach to understanding block caving geomechanics

Abstract. Block caving is an underground mining method of great importance to the future extraction of suitable, large, low-grade deposits due to high production rate potential and low operating cost. Block caving success relies on cave propagation, which is governed by the caving geomechanics operating at a location in space and time.Block cave mining method poses unique ventilation challenges compared to other underground metal mining methods. This research study focuses on assessing the airow behavior in regulated airow distribution systems by developing a 1:100 scaled block cave experimental model and a numerical model.
