THE EFFECT OF MESH DEPENDENCY ON THE CAVED MODELLING OF BLOCK CAVING METHOD

Continuous caving is one of important factor for the success of a block caving operation. The caving process can be modelled by using Finite Element Method (FEM) with strain-softening material behavior in Rocscience Phase2 8.0 software. However the results are highly depend on the mesh number (mesh...
