  • 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 ...
  • Legote, C. (Southern African Institute of Mining and Metallurgy, 2015-04)
    This paper investigates the conditions leading to the indefinite termination of production in four critical primary panels at an underground coal mining operation, the observed shortcomings in the mining approach, and ...
  • Du Plessis, Michael; Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2018-03)
    Crush pillars have been extensively applied on the Merensky Reef horizon since the late 1970s. Once in a crushed state, the residual strength of the pillar provides a local support function and must support the hangingwall to ...
  • Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, R.C.W. (Southern African Institute of Mining and Metallurgy, 2015-12)
    Determining the efficiency of a surface coal mine operation is an essential activity, which can help in deciding on the optimal use of input resources, including effective capital allocation, in generating a desired ...
  • 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 ...
  • 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 ...
  • Jooste, Yolande (University of Pretoria, 2013)
    Scattered mining was practised on Kusasalethu Mine (previously Elandsrand Gold Mine) prior to 1998, but as mining proceeded deeper, it was no longer a feasible option. The scattered mining method would have resulted in ...
  • Napier, J.A.L. (John); Malan, D.F. (Daniel Francois) (Southern African Institute of Mining and Metallurgy, 2011-12)
    A number of issues relating to the computational aspects of pillar design are addressed in this paper. The computation of average pillar stress values is important when attempting to establish criteria for pillar design ...
  • Kempson, William James (University of Pretoria, 2012-10-04)
    As a result of the rising electrical energy costs in South Africa, a method was sought to reduce the overall electrical consumption of typical shaft systems. A typical shaft configuration was analysed and the primary energy ...
  • 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 ...
  • Kempson, William James; Webber-Youngman, R.C.W.; Meyer, Josua P. (Southern African Institute of Mining and Metallurgy, 2013-12)
    As a result of the rising electrical energy costs in South Africa, a method was sought to reduce the overall electrical consumption of typical shaft systems. A typical shaft configuration was analysed and the primary ...
  • De Jager, F.C.; Steyn, Hendrik (Journal of Contemporary Management, 2013)
    This paper compares the organisational strategic drivers of a South African mining house with those of industries abroad. It furthermore compares the key competencies or capabilities of the mining house with those of the ...
  • 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 ...
  • Bartlett, Patrick John (University of Pretoria, 1998)
    Premier Diamond mine had to plan, develop and operate a low cost, mass mining method to recover extensive ore reserves below a 75 metre thick, dipping gabbro sill. The mining method had to preclude the extraction of as ...
  • 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 ...
  • Khanal, M.; McPhee, R.; Belle, B.; Brisbane, P.; Kathage, B. (Springer, 2019-01)
    A review of various real time temperature monitoring devices available for use in underground coal mines in Queensland was conducted. To investigate the fit-for-purpose of the intrinsically safe (IS) instrument, laboratory ...
  • 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 ...
