(Southern African Institute of Mining and Metallurgy, 2019-10)The mining industry of the 21st century needs a new kind of leader as certain leadership styles and most leadership models currently employed in the world, and also in South Africa, are not sustainable. This article ...

A critical investigation into missing persons in underground mines and related tracking technology (University of Pretoria, 2018)Even though mining has always been at the heart of the economy, it is also regarded as one of the most hazardous industries. Miners and any other persons who work underground can, not only be fatally injured during mining ...
-
(University of Pretoria, 2018)Conventional drill-and-blast practice in deep-level hard rock mining impacts negatively on the immediate environment and alternatives are frequently sought for efficient, continuous, automated and safe rock breaking. The ...
-
(Southern African Institute of Mining and Metallurgy, 2015-12)Preventing the propagation of methane or coal dust explosions through the use of active explosion-suppression systems remains one of the most underutilised explosion controls in underground coal mines. As part of the ...
-
(University of Pretoria, 2014-01)Mining is a hugely expensive process and unlike manufacturing is based on an ever diminishing resource. It requires a continuous infusion of capital to sustain production. A myriad of factors, from the volatility of the ...
-
The application of the analytical hierarchical process in complex mining engineering design problems (Southern African Institute of Mining and Metallurgy, 2011-12)Mining engineers frequently encounter complex design problems for which the critical components of the design are difficult to quantify or compare. Teams of people typically work on these designs and human perceptions ...
-
(Taylor & Francis, 2012-06)There is mounting evidence to show that engineers need more than technical skills to succeed in industry. In this paper we describe a curriculum innovation in which so-called “soft” skills, specifically inter-personal ...
-
(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 ...
-
(Southern African Institute of Mining and Metallurgy, 2010-04)Kriel Colliery has experienced some sub-standard blast results on the overburden. Blast results are considered poor when the fragmentation is too big, back break into the new highwall, capping is experienced and/or ...
-
(Southern African Institute of Mining and Metallurgy, 2023-05)We propose a layout design for the UG2 Reef where weak geological alteration layers are present. The collapse of the Everest platinum mine in South Africa indicated that these layers substantially weaken the pillars. The ...
-
(Elsevier, 2023-10)This paper investigates the use of a novel time-dependent bulking model in a displacement discontinuity code to simulate the convergence between the roof and the floor of deep tabular stopes. This study is important as ...
-
(Southern African Institute of Mining and Metallurgy, 2023-05)The limit equilibrium model, used in displacement discontinuity codes, is a popular method to simulate pillar failure. This paper investigates the use of physical modelling to calibrate this model. For the experiments, ...
-
A case study of geotechnical conditions affecting mining-induced seismicity in a deep tabular mine (Southern African Institute of Mining and Metallurgy, 2022-03)Seismic risk in the deep gold mines of South Africa has been studied for many decades. A clear understanding of the effect of geotechnical conditions on the seismic hazard nevertheless remains elusive. Certain reef types ...

(Mine Ventilation Society of South Africa, 2007-10)No abstract available.
-
(University of Pretoria, 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 ...
-
(Southern African Institute of Mining and Metallurgy, 2012-04)The utilization of centralized blasting systems is progressively becoming a feature of the South African mining industry, owing to increased pressure from the Department of Mineral Resources (DMR) to ensure safer blasting ...
-
(Southern African Institute of Mining and Metallurgy, 2023-04)Flyrock remains a significant threat to the health and safety of mine employees and integrity of infrastructure, as well as to the safety of the neighbouring communities and their property. This investigation was motivated ...
-
(University of Pretoria, 2006-12-01)Gullies have been regarded as the "artery" in mining because they provide the only access route for material, people and ore in stopes. It thus becomes vital to provide the industry with suitable guidelines for gully ...
-
(Southern African Institute of Mining and Metallurgy, 2013-04)Following the blasting fatality on 17 December 2009, Landau Colliery was forced to change from the blasting practices that had been utilized since the start-up of the mine. Since then, attempts have been made to optimize ...
