  • Recent advances in dust control technology on South African underground coal mines 
    Belle, Bharath K.; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 2002-10)
    Despite the much-heralded arrival of the new millennium, improving mine health and safety remains an enormous challenge. Considerable progress with environmental (dust and methane) control in South African mines has ...
  • A review of EN 16907 on earthworks (extractive waste) in the context of South African mine residues 
    Hortkorn, F.; Narainsamy, Yashay (Southern African Institute of Mining and Metallurgy, 2022-06)
    Rather quietly, a new generation of European norms dealing with earthworks has been developed over the past few years, in particular a part of EN 16907 pertaining to extractive waste. Whereas the majority of the parts ...
  • Risk factors limiting access to formal financing : perceptions from artisanal and small-scale mining (ASM) operators in Nigeria 
    Eniowo, O.D.; Kilambo, Sixta R.; Meyer, L.D. (Elsevier, 2022-12)
    This paper reflects critically on why individuals engaged in artisanal and small-scale mining (ASM) struggle to obtain formal loans. Several studies have concentrated on the perceptions of formal lenders on the risks ...
  • Risks and challenges affecting opencast pillar mining in previously mined underground bord and pillar workings 
    Ngwenyama, Philani Larrance; De Graaf, Wolter Willem (Southern African Institute of Mining and Metallurgy, 2021-12)
    South Africa is one of the leading producers and exporters of coal globally. A significant amount of the country’s production is obtained from previously mined underground bord and pillar workings. This coal is in the ...
  • Rock engineering aspects of a modified mining sequence in a dip pillar layout at a deep gold mine 
    Jooste, Yvonne; Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2015-10)
    Scattered mining was practised on Kusasalethu Mine (previously Elandsrand Gold Mine) prior to 1998, but at deeper mining levels it was no longer feasible, since it would have resulted in unacceptably high stress levels ...
  • Rockburst support in shallow-dipping tabular stopes at great depth 
    Malan, D.F. (Daniel Francois); Napier, J.A.L. (John) (Elsevier, 2018-12)
    This paper investigates the unique problems associated with the design of rockburst support for shallow-dipping tabular excavations. These designs are particularly problematic when the stoping width is very small. In steep ...
  • 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)
