  • 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 ...
  • 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 ...
  • Pasch, O.; Uludag, S. (Southern African Institute of Mining and Metallurgy, 2018-05)
    The current coal mining climate is characterized by coal price volatility, political instability, high labour costs, and increasing operational costs. This is exacerbated by a steady decline in the growth of global coal ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Ngwenyama, P.L. (Philani); De Graaf, W.W. (Wolter); Preis, E.P. (Eugene) (Southern African Institute of Mining and Metallurgy, 2017-03)
    The depletion of coal reserves in the Witbank coalfield in Mpumalanga Province has resulted in mining companies exploring the possibilities of extracting coal pillars. These are pillars that were left behind for hangingwall ...
  • 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. ...
  • 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 ...
  • Huisamen, Altus; Wolkersdorfer, Christian (Elsevier, 2016-07)
    A method for the geochemical modelling of transient contaminant release from rehabilitated opencast coal mines, including calibration against existing data, is proposed. The need for such a methodology is illustrated by a ...
  • Webber-Youngman, R.C.W.; Van Heerden, G. (Southern African Institute of Mining and Metallurgy, 2016-05)
    This article describes the re-engineering principles applied in the design of a personnel transportation system for the Bafokeng Rasimone Platinum Mine in the Rustenburg area of South Africa. It incorporates conveyor belt ...
  • 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 ...
  • Belle, B.K.; Du Plessis, J.J.L.; Oberholzer, J.W. (Mine Ventilation Society of South Africa, 2000-01)
    After initial studies by the CSIR indicating that a discrepancy exists in the dust concentration results between gravimetric dust samplers, alternative instruments or methods were sought. In the study that followed; it ...
  • Belle, B.K.; Du Plessis, J.J.L.; Van Zyl, F.J. (Mine Ventilation Society of South Africa, 2000-04)
    The changing and stricter regulatory environment has caused the mining industries in South Africa to re-look at their individual mine health and safety departments. In 1997, after the report of the Leon Commission of ...
  • Belle, Bharath K.; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 1999-01)
    The project was planned in two phases. The first phase involved laboratory tests on a continuous miner model for different ventilation and spray systems at the newly built ventilation simulation tunnel at the Klopperbos ...
  • Biffi, Marco; Marx, Wynand; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 2006-10)
    The FutureMine Collaborative Research Initiative has been successfully completed after three years of activity. The main objective of this initiative was to provide applications of research previously undertaken in ...

  • Du Plessis, J.J.L.; Potgieter, S.A.J. (Mine Ventilation Society of South Africa, 2016-07)
    Spotters and samplers working around surface drill rigs can be exposed to high dust concentrations. In this study it was found that individuals were exposed to as much as 14.2 mg/m3, which exceeds the Occupational ...
  • Du Plessis, J.J.L.; Janse van Rensburg, L.; Jansen van Rensburg, L.P. (Mine Ventilation Society of South Africa, 2016-04)
    Dust emissions from mining activities and their impact on the surrounding environment have been and remain one of the major environmental impacts associated with surface mining. Dust emissions caused by the transportation ...
  • Du Plessis, J.J.L.; Scott, D.; Moorcroft, H.E.S. (Mine Ventilation Society of South Africa, 2006-07)
    The increasing mining depths of South African gold mine deposits are resulting in ever-increasing heat loads associated with depth and the geothermal gradient. Together with changes in the mining horizons brought about ...
