Influence of boundary conditions in DEM models of sublevel caving on dilution and recovery
(UNDERGROUND MINING ENGINEERING, 2018-10)
Discrete element modelling is common approach for analysis of
dynamical processes that include granular materials. Method is commonly applied
for the modeling of the gravity flow of the broken rock in caving operations.
Herein, ...
Proposal of 2D finite element model for square pillar stability analysis
(UNDERGROUND MINING ENGINEERING, 2018)
It is suggested that 2D finite element method models are used for square
pillar stability analysis. Equivalent width of strip pillar that is represented by FE
models is determined from tributary area method by introducing ...
