    Crush pillars are used as part of the stope support in intermediate depth tabular mining stopes. Crush pillar design should ensure that the pillars crush when formed at the mining face. This behaviour of the pillars is ...

    In coal mining, spontaneous combustion can occur in many areas such as stockpiles, underground workings, waste dumps, coal faces, in-pit ramps and backfill areas. Spontaneous combustion has been defined as an oxidation ...
  • Budeba, M.D. (2016)
    The purpose of this research is to formulate mathematical models for assisting the management of either a new or operating surface coal mine to assess its competitiveness relative to other coal producers for a given market ...
  • 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 ...

    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 ...

    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 ...

    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. ...

    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 ...
  • Bartlett, Patrick John (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 ...
  • Maritz, Jan Abram (2015)
    In mining, the loading environment on pillars is highly complex with combinations of normal and shear stresses. It is also understood that with an active and working face, constant redistribution of stresses will occur to ...
  • 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 ...
