Ingham, M; Das, Sonali; Yadavalli, S(UNISA, 2017-10)
This paper identified change points in the production volumes and sales of various Industrial Metals in South Africa from the period 2003 – 2016. The socio-economic environment in which the mining sector operates is ...
The deployment of self-contained self-rescuers (SCSRs) together with the location of the refuge bays is part of well devised emergency evacuation procedures. For these to be successful, workers have to conversant with and ...
Roberts, David P(Southern African Institute of Mining and Metallurgy (SAIMM), 2017-07)
Bore-and-fill mining was implemented at a pilot site in Tau Tona mine’s shaft pillar on 97 level. Observations, scan data and measurements from this site were used to calibrate an inelastic numerical model of bore-and-fill ...
This article provides guidance to technical and non-technical coastal practitioner regarding the required precision of airborne lidar data for the typical coastal applications, output formats and value-added products. It ...
The focus of this paper is the manufacturing of a low-cost hybrid paper-based potentiostat. Potentiostats exhibit high sensitivity, and can be used for a variety of applications. The results highlight the functionality of ...
Ilgner, H(Wroclaw University of Environmental and Life Sciences, 2017-09)
The paper describes the extensive field evaluations of the “Settled Bed Detector” on different mine sites over a 12-month period. Applications range from cemented backfill, a well-graded magnetite product, coarse phosphate ...
Poor living conditions are a consequence of the history of the South African mining industry (SAMI), despite legislation having been implemented to attempt to address this challenge. This paper describes the living conditions ...
Localization is important for a wide range of industries and applications. In underground mining, for instance, it is helpful to know the miners’ locations, particularly in emergency situations. One way this can be achieved ...
Pretorius, Cecilia J(The Mine Ventilation Society of South Africa, 2017-07)
Circumstances may dictate that samples from mining operations are analysed for unknown compounds that are potentially harmful to humans. These circumstances may be out of the ordinary, unique or isolated incidents. Emergency ...
Cementitious grout support packs are usually assessed for their strength and durability from a safety perspective. Formulations of these packs range from cement mixed with water to resin-based formulations. Over time, these ...

Coal beneficiation in South Africa is currently conducted mostly on a wet “float and sink” basis. This process is heavily water intensive and also potentially polluting. Dry beneficiation alternatives are being sought. The ...
Pretorius, Cecilia J(Mine Ventilation Society of South Africa (MVSSA), 2016-04)
The objective of this study was to find a parameter in diesel and oil analysis of underground mining vehicles that can be correlated with personal diesel particulate matter (DPM) exposure and used as part of an engine ...
Mahlangu, Vusi J; Pretorius, Cecilia J; Ndibewu, PP(The Mine Ventilation Society of South Africa, 2016-09)
This paper presents qualitative analysis results of diesel particulate matter (DPM) from various mining commodities in South Africa. The objective of this work was to determine the concentrations of elements in DPM samples. ...
The aim of this study for the Transvaal and Orange Free State Chamber of Mines Research Organization was to examine the heat stroke position at the end of 1964 in terms of the trends in the numbers of stopes and development ...
In this report for the Transvaal and Orange Free State Chamber of Mines Research Organization, a detailed analysis is made of the effect of different metabolic rates, corresponding to light, moderate and hard work, on the ...
The report of the number of labourers working under conditions of high wet bulb temperatures has increased over the past ten years, and consequently, the need for acclimatizing labourers is greater than ever. The introduction ...
This report is intended primarily for ventilation staff on mines, but is also of importance to management. In the gold mining industry the assessment of heat stress is likely to be for one of three purposes: to assess ...
South African coal-fired power stations rely on the use of low grade bituminous coal for electricity generation. During coal combustion processes, this type of coal generates large volume of waste materials which include ...
Following a visit to the South African mining industry and the Chambers Research Organization, the author has presented a number of observations on various aspects of mining and mining research in the Republic. These ...
The technique developed on the laboratory for assessing the progress of decay in individual test poles 3 ft. in length and 5 ins. in diameter by the periodic measurement of their resistance to bending, has been further ...
