(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 ...
-
(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 ...
-
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 ...
-
(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 ...
-
(Southern African Institute of Mining and Metallurgy, 2017-07)It is vital for organizations and individual operations to have access to a platform with technology-related information to consider for further research and development. This paper presents a technology map that ...
-
(Southern African Institute of Mining and Metallurgy, 2017-08)The Chamber of Mines of South Africa (CoMSA) Certificates of Competency (CoCs) were introduced to standardize stand-alone in-house qualifications for persons working in the South African Mining and Minerals Industries ...
-
(Southern African Institute of Mining and Metallurgy, 2017-03)The depletion of coal reserves in the Witbank coalfield in Mpumalanga Province has resulted in mining companies exploring the possibilities of extracting coal pillars. These are pillars that were left behind for hangingwall ...
-
(Southern African Institute of Mining and Metallurgy, 2017-06)Pillar design for underground mining is typically done using empirical formulae or numerical modelling. Practical experience and recent literature, nevertheless, illustrate the shortcomings of these design approaches. ...
-
(Southern African Institute of Mining and Metallurgy, 2017-04)Gomes Sand is a quarry operation that produces sand and aggregate for the construction industry. The quarry is experiencing inconsistencies in the fragmentation and poor pit conditions as a result of poor drilling ...
-
(Elsevier, 2016-07)A method for the geochemical modelling of transient contaminant release from rehabilitated opencast coal mines, including calibration against existing data, is proposed. The need for such a methodology is illustrated by a ...
-
(Southern African Institute of Mining and Metallurgy, 2016-05)This article describes the re-engineering principles applied in the design of a personnel transportation system for the Bafokeng Rasimone Platinum Mine in the Rustenburg area of South Africa. It incorporates conveyor belt ...
-
(Mine Ventilation Society of South Africa, 2002-10)Despite the much-heralded arrival of the new millennium, improving mine health and safety remains an enormous challenge. Considerable progress with environmental (dust and methane) control in South African mines has ...
-
(Mine Ventilation Society of South Africa, 2000-01)After initial studies by the CSIR indicating that a discrepancy exists in the dust concentration results between gravimetric dust samplers, alternative instruments or methods were sought. In the study that followed; it ...
-
Hood type dust control systems on continuous miner (CM) in an underground bord and pillar coal mine (Mine Ventilation Society of South Africa, 2000-04)The changing and stricter regulatory environment has caused the mining industries in South Africa to re-look at their individual mine health and safety departments. In 1997, after the report of the Leon Commission of ...
