Experimental quantification of hang-up for block caving applications
(Elsevier, 2016)
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 ...
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, ...
Gravity flow and fragmentation modeling in Block Caving
(Universidad de Chile, 2022)
In block caving, the behavior of gravity flow is fundamental in mine design and pla nning. However, the great number of variables that influence this large scale phenomenon are difficult to study directly in the field. ...
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 ...
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 ...
Fenomenología agua-barro y simulación de estrategias operacionales para mitigar su ingreso en minas block/panel caving
(Universidad Andrés Bello, 2018)
El fenómeno “Agua-Barro” está presente en toda operación minera subterránea, y se es considerado como uno de los principales riesgos asociados a este tipo de operaciones, ya que estas son susceptibles al ingreso ...
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 ...
