  • The effect of scale and shape on the strength of Merensky Reef samples 
    Williams, Stephen Bruce (University of Pretoria, 2007-11-09)
    In general, as the uniaxial compressive strength of rock samples is tested, the uniaxial strength of the rock decreases with increasing sample size until a strength is reached beyond which no further decrease in strength ...
  • The effect of shear stresses on pillar strength 
    Maritz, Jan Abram (University of Pretoria, 2015)
    In mining, the loading environment on pillars is highly complex with combinations of normal and shear stresses. It is also understood that with an active and working face, constant redistribution of stresses will occur to ...
  • Effectiveness of applying dust suppression palliatives on haul roads 
    Du Plessis, J.J.L.; Janse van Rensburg, L.; Jansen van Rensburg, L.P. (Mine Ventilation Society of South Africa, 2016-04)
    Dust emissions from mining activities and their impact on the surrounding environment have been and remain one of the major environmental impacts associated with surface mining. Dust emissions caused by the transportation ...
  • Efficient use of energy in the ventilation and cooling of mines 
    Du Plessis, J.J.L.; Marx, W.M.; Nell, C. (Southern African Institute of Mining and Metallurgy, 2014-12)

  • Evaluation and design of optimum support systems in South African collieries using the probabilistic design approach 
    Canbulat, Ismet (University of Pretoria, 2008-08-06)
    This thesis addresses the problem of designing roof support systems in coal mines. When designing the roof support, it is necessary to account for the uncertainties that are inherently exist within the rock mass and support ...
  • Evaluation of a continuous miner half-curtain dust control system in a South African underground coal mine 
    Belle, Bharath K.; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 1999-01)
    The project was planned in two phases. The first phase involved laboratory tests on a continuous miner model for different ventilation and spray systems at the newly built ventilation simulation tunnel at the Klopperbos ...
  • Evaluation of a limit equilibrium model to simulate crush pillar behaviour 
    Du Plessis, M.; Malan, D.F. (Daniel Francois); Napier, J.A.L. (John) (Southern African Institute of Mining and Metallurgy, 2011-12)
    This paper describes the evaluation of a limit equilibrium model to simulate the behaviour of crush pillars in platinum mines. An analytical model was derived to calculate the residual average pillar stress (APS) values ...
  • Evaluation of some optimum moisture and binder conditions for coal fines briquetting 
    Venter, P.; Naude, Natasia (Southern African Institute of Mining and Metallurgy, 2015-04)
    Coal mining is a thriving industry and 53% of the coal mined in South Africa is used for electricity generation. Mechanization has made coal mining more efficient, but fines generation has subsequently increased. Up to ...
  • Evaluation of stope support using a rockmass stiffness approach 
    Pretorius, Martin Johannes (University of Pretoria, 2006-05-19)
    The study that is described in this thesis deals with stope support design from a rockmass stiffness approach. Three models were developed and combined into a single one in the third part of the study in an attempt to ...
  • The experience of using virtual reality for interactive spatial visualisation of environmental data 
    Bosman, Isak de Villiers; Smith, Annique Elizabeth; Ka, Kwan Sui Dave; De Beer, Koos; Maritz, J.A. (Jan) (CEUR-WS, 2023)
    Virtual reality possesses various properties that have the potential to be beneficial for the visualisation of spatial data, including intuitive gestural affordances for looking around and interacting with data and the ...
