  • Angelov, A.A.; Naidoo, K. (Southern African Institute of Mining and Metallurgy, 2010-05)
    This paper presents a unique method of monitoring the effectiveness of the planning process as well as the execution of mine plans. The method primarily determines the degree of deviation from the original mine plans ...
  • Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, R.C.W.; Shafiee, Shahriar (Taylor & Francis, 2017)
    Mining is a competitive business with many players. The survival of a mine in the business is determined by its efficiency and cost-effectiveness relative to the other producers. Both new and operating mines should select ...
  • De Graaf, W.W. (Wolter); Spiteri, W. (Southern African Institute of Mining and Metallurgy, 2018-08)
    Hydraulic rock-splitting cylinders have proved successful in numerous civil and construction applications. The purpose of this study was to conduct a preliminary qualitative evaluation of the applicability of the ...
  • Maritz, J.A. (Jan) (Southern African Institute of Mining and Metallurgy, 2014-12)
    Since the dawn of mining, pillars have been used as primary support to ensure stable workings. Early designs were based on trial and error, after which more scientific means developed over time. A vast amount of progress ...
  • Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, R.C.W. (Southern African Institute of Mining and Metallurgy, 2015-11)
    Cost estimation for surface coal mines is a critical practice that affects both profitability and competitiveness. New mines require these costs to be estimated using available information before a project begins. ...
  • Lombard, K. (Southern African Institute of Mining and Metallurgy, 2015-04)
    ‘Roof support awaiting time’ (RSAT) is a term used at Goedehoop Colliery’s Simunye Shaft to describe the potential production time lost due to the continuous miner (CM) standing idle waiting for roof support to catch ...
  • Malan, D.F. (Daniel Francois); Napier, J.A.L. (John) (Southern African Institute of Mining and Metallurgy, 2018-03)
    Time-dependent closure data in deep hard-rock mines appears to be a useful diagnostic measure of rock behaviour. Understanding this behaviour may lead to enhanced design criteria and modelling tools. This paper investigates ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • 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 ...
  • 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 ...
  • 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, ...
  • 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 ...
  • 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 ...
