  • The Sasol Engineering and Leadership Academy 
    Knobbs, Clive G.; Gerryts, Erna W.; Kagogo, T.; Neser, M. (Southern African Institute of Mining and Metallurgy, 2014-12)
    Contrary to the way it is often portrayed, the average organization or company is far from being a cold, calculating machine. It is actually a highly emotive place where interaction with people is a fundamental part of ...
  • Simulation of tabular mine face advance rates using a simplified fracture zone model 
    Napier, J.A.L. (John); Malan, D.F. (Daniel Francois) (Elsevier, 2018-09)
    This paper describes a method to determine the time-dependent stability of the fracture zone near the edges of tabular excavation layouts when different mining rates and face advance increment lengths are scheduled. Some ...
  • Simulation of time-dependent crush pillar behaviour in tabular platinum mines 
    Napier, J.A.L. (John); Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2012-08)
    It has been established that significant time-dependent stope convergence may occur over time periods of hours and days in certain hard-rock gold and platinum mines. The source of this time-dependent behaviour appears ...
  • Some rock engineering aspects of multi-reef pillar extraction on the Ventersdorp Contact Reef 
    Esterhuyse, J.C.; Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2018-12)
    Mining in the Carletonville area of the Witwatersrand Basin predates 1934. Owing to the depletion of higher grade ore, the current activities focus increasingly on the extraction of lower grade secondary reefs as well as ...
  • Specific gas emissions in Bowen Basin longwall mines, Australia 
    Qu, Qingdong; Balusu, Rao; Belle, Bharath K. (Elsevier, 2022-09)
    Longwall coal mines in the Bowen Basin of Australia are highly productive and gassy, comprising many coal seams above the working seam. Predictive modelling of specific gas emission (SGE) using the conventional Winter model ...
  • Status of the phasing out of the Chamber of Mines of South Africa Certificates of Competency 
    Grobler, Hennie; Maritz, J.A. (Jan) (Southern African Institute of Mining and Metallurgy, 2017-08)
    The Chamber of Mines of South Africa (CoMSA) Certificates of Competency (CoCs) were introduced to standardize stand-alone in-house qualifications for persons working in the South African Mining and Minerals Industries ...
  • Strapping of pillars with cables to enhance pillar stability 
    Alejano, L.R.; Arzua, J.; Castro-Filgueira, U.; Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2017-06)
    Pillar design for underground mining is typically done using empirical formulae or numerical modelling. Practical experience and recent literature, nevertheless, illustrate the shortcomings of these design approaches. ...
  • Sub-standard practices : effects on safety performance in South African gold mines 
    Kleyn, G.; Du Plessis, J.J.L. (Southern African Institute of Mining and Metallurgy, 2016-04)
    Sub-standard practices and their adverse impact on safety performance remain a challenge in the South African gold mining industry. The purpose of this study was to investigate the root causes of sub-standard practices and ...
  • Surface fan operational cost saving using purposely designed fans 
    Viljoen, A.; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 2019-01)
    The use of high powered catalogued auxiliary fans to meet the ventilation requirements of fairly shallow mines is common practice and often is not an energy efficient ventilation solution. This paper describes the ...
  • A technology map to facilitate the process of mine modernization throughout the mining cycle 
    Jacobs, Jonatan; Webber-Youngman, R.C.W. (Southern African Institute of Mining and Metallurgy, 2017-07)
    It is vital for organizations and individual operations to have access to a platform with technology-related information to consider for further research and development. This paper presents a technology map that ...
  • Testing of an on-board active suppression system for French mining conditions 
    Du Plessis, J.J.L.; Van Dijk, R.L.S. (Southern African Institute of Mining and Metallurgy, 2001-10)
    The French research institute, INERIS, requested the assistance of the CSIR’s Division of Mining Technology in developing further precautionary measures against explosions in their collieries. In response to this approach, ...
  • 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 ...
  • Towards a generalizable project readiness assessment methodology for the mining industry 
    Mulder, Hardus; Bekker, M.C. (Michiel Christiaan) (Southern African Institute of Mining and Metallurgy, 2022-09)
    The principal objective of this investigation was to conduct a thorough literature review on the status of project readiness mechanisms, tools, techniques, and frameworks for mining projects. The review aimed at identifying ...
  • A trade-off study between down-dip and breast mining on the Merensky Reef at Khomanani 2 
    Ferreira, S.J.S. (Southern African Institute of Mining and Metallurgy, 2012-04)
    Anglo American Platinum’s Khomanani 2 shaft changed over from down-dip mining to breast mining in 2004. The changeover was made to ensure that production targets were met, as it was said that predevelopment for down-dip ...
