  • Crush pillar support - designing for controlled pillar failure 
    Du Plessis, M.; Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2015-06)
    The aim of any mine design is to ensure that the excavations remain stable for the period they will be in use. Various pillar systems are used to ensure that underground stopes remain stable and that mining activities ...
  • 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 ...
  • Investigating the use of polymer-modified cementitious thin spray-on liners as stope face support 
    Du Plessis, M.; Malan, D.F. (Daniel Francois) (Elsevier, 2021-06)
    This paper investigates the use of a thin spray-on liner (TSL) as stope face support in narrow width tabular stopes. The application of areal support is difficult in these stopes because of the small stoping width and the ...
