OHMS has the capability to perform numerical modelling at any point in a mine’s life cycle or project study phase for open cast or underground mines.
Geological structures, anisotropy, heterogeneous rock masses, stress models, excavation geometries, constitutive behaviour, backfill and support elements can be incorporated in the assessments.
The numerical methods that is employed by the OHMS Modelling Division include finite element, boundary element (displacement discontinuity or fictitious force methods), and discrete element.
The numerical modelling packages and methods, which we use are based on the (i) finite element, (ii) boundary element (displacement discontinuity/fictitious force), (iii) discrete element, (iv) limit equilibrium, (iv) keyblock , (v) Monte-Carlo simulations, (vi) Point Estimate (vii) Rigid Body Fall Dynamic methods and codes, respectively.
The specific software packages include:
