  • Van Heerden, G.M.J.; Theron, W.J. (Southern African Institute of Mining and Metallurgy, 2011)
    The purpose of the paper is to give an introduction to the concept of fatigue and its causes in the mining industry. By knowing the fundamental role it plays, together with its dynamics, can positively contribute to ...
  • Budeba, M.D.; Joubert, Johannes Willem; Webber-Youngman, R.C.W.; Shafiee, Shahriar (Taylor & Francis, 2016-03)
    Mining is a competitive business with many players. The survival of a mine in the business is determined by its e ciency and cost-e ectiveness relative to the other producers. Both new and operating mines should select ...
  • Lindeque, G.C. (Southern African Institute of Mining and Metallurgy, 2016-04)
    A downward trend in tyre life on haul trucks at an open pit iron ore mine prompted an investigation into the current tyre management strategy in order to improve tyre life. ‘Best practice’ was compared to the current ...
  • 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 ...
  • Du Toit, J.; Cromarty, Robert Douglas; Garbers-Craig, Andrie Mariana (Southern African Institute of Mining and Metallurgy, 2016-04)
    Penetration of matte into tap-hole bricks causes detrimental refractory wear, which can lead to furnace breakouts. The ability of the tap-hole clay to form a protective layer on the brick, thereby limiting matte ...
  • 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. ...
  • Jooste, Yvonne; Malan, D.F. (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.; Aydan, Omer; Ito, Takashi; Ozbay, Ugur; Kwasniewski, M.; Shariar, K.; Okuno, T.; Ozgenoglu, A.; Okada, T. (Springer, 2014-01)
    It is important to note that creep is only one aspect of the time-dependent behavior of rocks. In Fig. 1, three cases are illustrated with respect to the complete stress–strain curve: creep, i.e., increasing strain when ...
  • Webber-Youngman, R.C.W.; Budeba, M.D.; Joubert, Johannes Willem (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 ...
  • Naude, Natasia; Venter, P. (Southern African Institute of Mining and Metallurgy, 2015-04)
    Coal mining is a thriving industry and 53% of the coal mined in South Africa is used for electricity generation. Mechanization has made coal mining more efficient, but fines generation has subsequently increased. Up to ...
  • 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 ...
  • Lombard, R. (Southern African Institute of Mining and Metallurgy, 2015-04)
    Water is a very important component in the production process at underground coal mines. Current unfavourable economic conditions have forced the coal mining industry to identify and address every possible bottleneck ...
  • 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.; Du Plessis, M. (Southern African Institute of Mining and Metallurgy, 2015-06)
    The aim of any mine design is to ensure that the excavations remain stable for the period they will be in use. Various pillar systems are used to ensure that underground stopes remain stable and that mining activities ...
  • 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 ...
  • Du Plessis, J.J.L.; Marx, W.M.; Nell, C. (Southern African Institute of Mining and Metallurgy, 2014-12)
    Escalating energy and electricity costs have become one of the largest drivers of expenditure in mining operations. Over the last eight years, energy costs have tripled when expressed as a percentage of total expenses in ...
  • Maritz, J.A. (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 ...
  • Weber, R. (Southern African Institute of Mining and Metallurgy, 2014)
    Methane explosions in underground coal mines are a major concern across the mining industry. After the Pike River disaster, Arnot Coal became even more aware of the explosion risk. To determine whether Arnot has adequate ...
  • Meyer, Josua P.; Webber-Youngman, R.C.W.; Kempson, William James (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 ...
  • Tonkin, C.J. (Southern African Institute of Mining and Metallurgy, 2013-04)
    Compressed air is widely used on South African gold mines. However, due to recent and proposed future electricity tariff increases it is quickly becoming too expensive to produce and use. Boxfront chute systems at ore ...
