  • 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 ...
  • An investigation into the fragmentation of blasted rock at Gomes Sand 
    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
