Productivity of a Continuous Mining System for Block Caving Mines
(Springer-Verlag Wien, 2017)
Block caving mining is one of the most cost-effective underground mining methods. The method has particular relevance in the Chilean mining industry, where approximately 40% of the Chilean national copper production comes ...
Experimental quantification of vertical stresses during gravity flow in block caving
(Elsevier, 2020)
Usually in block and panel caving mines, when the caving connects to the surface, monitoring of vertical stresses over production drifts is minimal due to the low probability of seismic events. However, when the stresses ...
Methodology for evaluation of mud rush risk in block caving mining
(Southern African institute mining metallurgy, 2017)
Mud rushes are sudden inflows of fine wet ore within underground mines; they can harm people and equipment as well as cause production delays. Block and panel caving mines are prone to mud rushes in their production levels, ...
Automation fundamentals of continuous mining system
(Taylor & Francis, 2015)
Even though block caving mining method is already the most economical underground mining
method for large massive ore bodies, it requires further technical advancements to also become a
practical method for deep deposits ...
Geotechnical characterization of ore related to mudrushes in block caving mining
(South African Institute of Mining and Metallurgy, 2017)
Mudrushes are sudden inflows of mud ore into underground miningfacilities. They may cause harm to people and equipment, productiondelays, dilution of ore, and mine closure. The aim of this work is to charac-terize, by ...
Experimental study of the influence of drawbell geometry on hang-ups in cave mine applications
(Springer, 2020)
Coarse arches are a common issue in caving mines where large fragments are expected. These arches interrupt ore flow in drawpoints, decreasing available draw area, and also increasing the possibility of non-uniform draw, ...
Blasting and preconditioning modelling in underground cave mines under high stress conditions
(2021)
Cave mining is an underground mass mining technique. The largest projects, which are known as 'super caves', produce hundreds of thousands of tons of ore per day, which involves large footprints with considerable column ...
Study of multiple draw-zone interaction in block caving mines by means of a large 3D physical model
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-10)
Current production level design guidelines in block caving mines are based on the concept of interaction of movement zones and the
spacing of draw-points at which mass flow is achieved. The limit of the isolated movement ...
Numerical Modelling of Water Flow Through Granular Material for Isolated and Simultaneous Extractions in Block Caving
(Springer-Verlag Wien, 2019)
© 2018, Springer-Verlag GmbH Austria, part of Springer Nature. In this work, we numerically solve the Brinkman–Darcy equation coupled to the granular kinematic model using the finite elements method in 2D, to describe the ...
Gravity flow characterization of fine granular material for Block Caving
(Elsevier Ltd, 2019)
© 2018 Elsevier Ltd Block and Panel Caving are based on the action of gravity for ore breakage and transport, so that material reaches the drawpoint through gravity flow. The study of caved rock flow is of vital importance ...
