Stacey, J.; Stacey, A.(The Southern African Institute of Mining and Metallurgy., 2014-11)
Large mining companies generally follow the distributed ownership
corporate model, with a board of directors responsible for decisions that
affect both shareholder value and stakeholders of the company. The board
is ...
Katakwa, T.P.; Musingwini, C.; Genc, B.(The Southern African Institute of Mining and Metallurgy., 2013-06)
The utilization of software is now inherent to virtually every activity along the mining value chain. However, apart from the software survey done by Gibbs in the 1990s and work on the extent of diffusion of information ...
Mohutsiwa, M.; Musingwini, C.(The Southern African Institute of Mining and Metallurgy., 2015-08)
Capital cost estimates are important in decisions on whether a project will be approved, mothballed, or abandoned. In South Africa, junior coal miners do not have extensive databases of historical projects from which to ...
Genc, B.; Musingwini, C.; Celik, T.(The Southern African Institute of Mining and Metallurgy., 2015-02)
This paper discusses a new methodology for defining and measuring mine planning software utilization in the South African gold mining sector within an evolving data-set framework. An initial data-set showing the mine ...
Nhleko, A.S.; Musingwini, C.(The Southern African Institute of Mining and Metallurgy., 2016-03)
Since the Global Financial Crisis (GFC) in mid-2008, capital has been more difficult to access. Mining projects must contend with projects from other industries for scarce capital. A decision to invest available capital ...
Genc, B.; Musingwini, C.; Celik, T.(The Southern African Institute of Mining and Metallurgy., 2016-03)
Mine planning software continues to be an important factor when it comes to the development of the South African mining industry. To contribute to this development, a new methodology to define and measure mine planning ...
Chabedi, C.K.; Zvarivadza, T.(The Southern African Institute of Mining and Metallurgy., 2016-11)
This paper discusses the difficulties associated with the potential exploitation of the deep multi-seam resources east of the Daarby fault in the Waterberg coalfield. The resources occur at a depth greater than 250 m and ...
Chikande, T.; Zvarivadza, T.(The Southern African Institute of Mining and Metallurgy., 2016-04)
Falls of ground pose costly hazards to personnel and equipment and thus measures should be taken to prevent them. This study endeavours to improve the support systems used in geotechnically poor ground at a Zimbabwean ...
Minnitt, R.C.A.(The Southern African Institute of Mining and Metallurgy., 2014)
Although not fully accepted in South Africa, the Theory of Sampling originally proposed by Pierre Gy is fast becoming the cornerstone of sampling practice throughout the world. The growing acceptance of Gy's Theory of ...
Minnitt, R.C.A.; Deutsch, C.V.(The Southern African Institute of Mining and Metallurgy., 2014)
Cokriging uses a sparsely sampled, but accurate and precise primary dataset, together with a more abundant secondary data-set, for example grades in a polymetallic orebody, containing both error and bias, to provide improved ...
Mphathiwa, N.; Cawood, F.T.(The Southern African Institute of Mining and Metallurgy., 2014)
When slope angles are designed during open pit optimization, there is a risk factor applied in steepening the slopes. The steepening of slope angles has implications for the safety and economics of the mining operation. ...
The University of the Witwatersrand School of Mining Engineering (Wits Mining) has its origins in the South African School of Mines, which was established in 1896. It is currently recognised as one of the world’s top mining ...
