  • The effect of overburden and confined stress state on cave mining propagation 
    Schoeman, Nicholas Kyle; Jacobsz, Schalk Willem; Kearsley, Elsabe P. (Southern African Institute of Mining and Metallurgy, 2022-11)
    A physical modelling approach was adopted to simulate the process of cave mining propagation at various horizontal to vertical stress state ratios, and image data was captured and used to characterize the resulting failure ...
  • Fly-by-Pi : open source closed-loop control for geotechnical centrifuge testing applications 
    Broekman, Andre; Jacobsz, Schalk Willem; Louw, Hendrik; Kearsley, Elsabe P.; Gaspar, Tiago Alexandre Valentim; Da Silva Burke, Talia Simone (Elsevier, 2020-10)
    Geotechnical centrifuges are valuable instruments for physical modelling of complex geotechnical problems in a controlled laboratory setting. In comparison to full-scale testing, scaled models are cost effective to construct ...
  • Fracture banding in caving mines 
    Cumming-Potvin, D.; Wesseloo, J.; Jacobsz, Schalk Willem; Kearsley, Elsabe P. (Southern African Institute of Mining and Metallurgy, 2016-08)
    The Duplancic model of caving is widely accepted in industry and is the framework within which most monitoring and numerical modelling results in caving mines are interpreted. As a result, the damage profile ahead of the ...
  • A geotechnical centrifuge for TUKS 
    Jacobsz, Schalk Willem (South African Institution of Civil Engineering, 2011-04)
    The Department of Civil Engineering at the University of Pretoria has recently been awarded a grant from the National Research Foundation (NRF) to acquire a geotechnical centrifuge. Geotechnical centrifuges are used ...
  • Partially saturated flow from sand into a discrete smooth open vertical fracture at the soil–rock interface : experimental studies 
    Brouwers, Luke Bernhard; Dippenaar, Matthys Alois (Springer, 2019-06)
    The two proposed conceptual models explaining partially saturated flow from soil into fractured rock in the intermediate fractured vadose zone have not been confirmed due to the difficulty involved in observing the soil–rock ...
  • Physical and mathematical modelling of ignition of small magnesium particles 
    Fedorov, A.V.; Shulgin, A.V.; Tropin, D.A. (International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, 2008)
    Paper presented at the 6th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, South Africa, 30 June - 2 July, 2008.
