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 ...
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 ...
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, ...
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 ...
Desarrollo de una Herramienta para Planificación de Largo Plazo en Block/Panel Caving
(Universidad de Chile, 2011)
Las metodologías actuales para la estimación de reservas en Block o Panel Caving se basan en principios de mezcla propuestos hace más de 25 años, cuando se intentó representar la física del flujo gravitacional mediante un ...
