(Southern African Institute of Mining and Metallurgy, 2020-01)This paper was compiled to highlight the need for additional research in the area of layout design criteria for deep gold mines. It describes aspects related to two popular design criteria used in the deep gold mines of ...
-
(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 ...
-
The impact of forensic laser scanning technology on incident investigations in the mining industry (Southern African Institute of Mining and Metallurgy, 2019-10)Risk assessments have been conducted in the South African mining industry over the past 20 years, but still we do not always correctly identify the root cause of an incident. An incident investigation is not only about ...
-
(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 ...
-
(University of Pretoria, 2019)Flyrock remains a significant risk to the health and safety of the mine’s employees and infrastructure as well as the safety of the neighbouring communities and their property. Losses and damages can result in significant ...
-
Structural mechanisms contributing to large-scale hangingwall instabilities on the UG2 reef horizon (University of Pretoria, 2019)Structural complexities, including regional geologic structures, low-angle structures, ramp structures and alteration zones contribute towards large-scale hangingwall or structural (pillar) instabilities experienced in ...
-
(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 ...
-
(Southern African Institute of Mining and Metallurgy, 2018-12)Mining in the Carletonville area of the Witwatersrand Basin predates 1934. Owing to the depletion of higher grade ore, the current activities focus increasingly on the extraction of lower grade secondary reefs as well as ...

Structural mechanisms contributing to large-scale hangingwall instabilities on the UG2 reef horizon (University of Pretoria, 2019)Structural complexities, including regional geologic structures, low-angle structures, ramp structures and alteration zones contribute towards large-scale hangingwall or structural (pillar) instabilities experienced in ...
-
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 ...
-
(University of Pretoria, 2018)In the past decades, attempts were made to build a systematic approach to mining method selection (MMS) Ooriad et al, (2018). This is because MMS is a complex and irreversible process. Since it can affect the economic ...
-
Reassessing continuous stope closure data using a limit equilibrium displacement discontinuity model (Southern African Institute of Mining and Metallurgy, 2018-03)Time-dependent closure data in deep hard-rock mines appears to be a useful diagnostic measure of rock behaviour. Understanding this behaviour may lead to enhanced design criteria and modelling tools. This paper investigates ...
-
(University of Pretoria, 2018)The process of mining is about executing a few, seemingly easy, routine activities with consistency and precision over an extended period of time. The research that has been conducted during the course of this study has ...
-
(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 ...
-
(Elsevier, 2018-09-03)This paper explores possible synergies between techniques used to minimise seismicity in deep South African gold mines and their applicability to control coal bumps. The paper gives a summary of the techniques used in ...
-
(Elsevier, 2018-12)This paper investigates the unique problems associated with the design of rockburst support for shallow-dipping tabular excavations. These designs are particularly problematic when the stoping width is very small. In steep ...
-
(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 ...
-
(Southern African Institute of Mining and Metallurgy, 2018-01)This article is based on the premise that the purpose of engineering education, in general, is to deliver engineering practitioners who are intellectually capable of identifying, structuring, and solving complex problems, ...
-
(Elsevier, 2018-09)This paper describes a method to determine the time-dependent stability of the fracture zone near the edges of tabular excavation layouts when different mining rates and face advance increment lengths are scheduled. Some ...
