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 ...
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. ...
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, ...
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 ...
Generación de material fino inducido por esfuerzo de corte y su aplicación a la fragmentación secundaria en Block Caving.
(Universidad de Concepción, 2024)
En métodos de hundimiento en minería subterránea, tal como el Block/Panel Caving, es de vital importancia medir y controlar las variables que tienen una gran repercusión en la rentabilidad y seguridad de la operación minera. ...
Petrologia das fraturas associadas a feições típicas de dissolução hipogênica na Formação Salitre, Bacia de Irecê, Bahia, Brasil
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2015-05-05)
The recognition of karst reservoirs in carbonate rocks has become
increasingly common. However, most karst features are small to be
recognized in seismic sections or larger than expected to be investigated with
borehole ...
Speleogenesis in quartzites from the Ibitipoca Range, southeastern Minas GeraisEspeleogênese em quartzitos da Serra do Ibitipoca, sudeste de Minas Gerais
(Centro de Ciências Matemáticas e da Natureza, Instituto de Geociências, Universidade Feder, 1997)
Modelo multivariable de ingreso de dilución en minería de Caving
(Universidad de Chile, 2021)
El método de explotación de Block/Panel Caving considera dentro de sus desafíos evitar o retrasar la entrada temprana de dilución, pues genera un perjuicio económico a los proyectos mineros y está asociada a eventos ...
Geoutouristic potential of Ibitipoca'S Park, southeastern of Minas Gerais StatePotencial geoturístico do Parque Estadual da Serra do Ibitipoca, sudeste do estado de Minas Gerais
(Centro de Ciências Matemáticas e da Natureza, Instituto de Geociências, Universidade Feder, 2012)
