    Gomes-Sebastiao, G.L.; De Graaf, W.W. (Wolter) (Southern African Institute of Mining and Metallurgy, 2017-04)
    Gomes Sand is a quarry operation that produces sand and aggregate for the construction industry. The quarry is experiencing inconsistencies in the fragmentation and poor pit conditions as a result of poor drilling ...
  • An investigation on underground transport roads and influence on safety and productivity at Khutala Colliery 
    Lehasa, S. (Southern African Institute of Mining and Metallurgy, 2012-04)
    The purpose of the project was to investigate the challenges faced by Khutala Colliery pertaining to underground road construction and maintenance. Furthermore the influence of these challenges on productivity and safety ...
  • ISRM suggested methods for determining the creep characteristics of rock 
    Aydan, Omer; Ito, Takashi; Ozbay, Ugur; Kwasniewski, M.; Shariar, K.; Okuno, T.; Ozgenoglu, A.; Malan, D.F. (Daniel Francois); Okada, T. (Springer, 2014-01)
    It is important to note that creep is only one aspect of the time-dependent behavior of rocks. In Fig. 1, three cases are illustrated with respect to the complete stress–strain curve: creep, i.e., increasing strain when ...
  • Journal impact factors - the good, the bad, and the ugly 
    Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2022-09)
    This paper provides an overview of the concepts of citations and journal impact factors, and the implications of these metrics for the Journal of the Southern African Institute of Mining and Metallurgy (JSAIMM). Two key ...
  • A limit equilibrium fracture zone model to investigate seismicity in coal mines 
    Malan, D.F. (Daniel Francois); Napier, J.A.L. (John) (Elsevier, 2018-09-03)
    This paper explores possible synergies between techniques used to minimise seismicity in deep South African gold mines and their applicability to control coal bumps. The paper gives a summary of the techniques used in ...
  • A limit equilibrium model of tabular mine pillar failure 
    Napier, J.A.L. (John); Malan, D.F. (Daniel Francois) (Springer, 2021-01)
    An improved understanding of pillar strength and pillar failure mechanisms is required to optimize tabular mine layout designs. The paper describes the application of a limit equilibrium model for pillar failure analysis. ...
  • Matte - tap-hole clay - refractory brick interaction in a PGM smelter 
    Du Toit, J.; Cromarty, Robert Douglas; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2016-04)
    Penetration of matte into tap-hole bricks causes detrimental refractory wear, which can lead to furnace breakouts. The ability of the tap-hole clay to form a protective layer on the brick, thereby limiting matte ...
