  • Blast optimization at Kriel Colliery 
    Neale, A.M. (Southern African Institute of Mining and Metallurgy, 2010-04)
    Kriel Colliery has experienced some sub-standard blast results on the overburden. Blast results are considered poor when the fragmentation is too big, back break into the new highwall, capping is experienced and/or ...
  • Continuous blasting improvements at Landau Colliery 
    Rakoma, M. (Southern African Institute of Mining and Metallurgy, 2013-04)
    Following the blasting fatality on 17 December 2009, Landau Colliery was forced to change from the blasting practices that had been utilized since the start-up of the mine. Since then, attempts have been made to optimize ...
  • Testing stemming performance, possible or not? 
    Boshoff, D.; Webber-Youngman, R.C.W. (Southern African Institute of Mining and Metallurgy, 2011-12)
    The ability of an explosive to break rock is influenced considerably by the extent of confinement in the blasthole. It is believed that confinement is improved by the use of adequate stemming. The aim of this paper is to ...
