  • Gurtunca, RG; Adams, DJ (CSIR, 1991-03)
    In situ measurements and numerical modelling based on elastic theory showed that backfill stresses are considerably higher than originally thought. This has led to a change in understanding of rockmass behaviour. After ...
  • Mendecki, AJ; Napier, JAL; Ilchev, A; Sellers, E (2001-06)
    Numerical modelling of rock-mass response to underground excavations is of vital importance for the decision-making process in designing and running a mine. Likewise, seismic monitoring with state-of-the-art local seismic ...
  • Govender, Nicolin; Gledhill, Irvy MA; Kok, S; Wilke, N (Colorado School of Mines, 2013-08)
    The protection of harbours and coastal infrastructure is of vital importance to South Africa. A major development in the design of packing strategies for breakwaters is numerical modelling, and the use of physics engines ...
  • Rusinga, F; Taigbenu, AE (Water Research Commission, 2005-01)
    Judicious management of a groundwater system requires an understanding of its hydrogeology and response to various recharge and pumping stresses. However, in developing countries, groundwater resource evaluations are ...
  • Loveday, PW; Long, CS; Forbes, A; Land, K (South African Conference on Computational and Applied Mechanics, 2008-03)
    An intra-cavity adaptive mirror is required to compensate for time-dependent phase aberrations to the laser beam, such as those caused by thermal lensing. A piezoelectric unimorph design can provide a small, low-cost ...
  • Lightfoot, N; Maccelari, M (1999-03)
    This report covers the production of a general reference handbook of numerical modelling for the South African mining industry, with particular reference to the gold and platinum industries. It also covers a research ...
  • Lightfoot, N; Maccelari, M (1999-09)
    The SIMRAC project GAP629 has two aspects. Firstly, the production of an updated edition of the guidebook Numerical Modelling of Mine Workings. The original document was launched to the South African mining industry in ...
  • Greben, JM; Cooper, Antony K; Gledhill, Irvy MA; de Villiers, R (CSIR, 2008-11)
    The authors have applied various numerical techniques to describe the stability of breakwater structures under the exposure of waves. These studies are intended to get a better understanding of the parameters playing a ...
  • Napier, JAL; Malan, DF (Australian Centre for Geomachanics, 2008-09)
    Some of the key problems facing rock engineers on mines in the Bushveld Complex are design of stable panel spans, optimum pillar dimensions and assessing hangingwall stability. A particularly difficult problem is encountered ...
