The ready availability of powerful desktop workstations, which
combine 3D real-time graphics and processing speed better than
that of supercomputers of a few years ago, now allows the
cost-effective solution of real world geomechanics and
underground mining strength simulations. The inclusion of
geotechnical factors such as rock joints and porous flow on
strength and stability are discussed together with the range of
available deformation and failure models for soil, rock and
concrete. This paper describes the capabilities provided by finite element
graphics and analysis software for modelling and sequential
investigation of both excavation and lining, or rock bolting,
construction sequences. Examples of the use of finite element
models in mining are also included in the paper, together with a
discussion of the required people, software and computer
hardware resources required to achieve timely and productive
results.
