Du Plessis, J.J.L. (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 ...

Du Plessis, J.J.L.; Van Greuning, D.C. (Southern African Institute of Mining and Metallurgy, 2011-12)Beatrix Gold Mine, a deep-level gold mine in the Free State province of South Africa, has the highest methane emission rate of any gold mine in the country. Methane is emitted from underground sources intersected during ...

Du Plessis, J.J.L.; Janse van Rensburg, L.; Jansen van Rensburg, L.P. (Mine Ventilation Society of South Africa, 2016-04)Dust emissions from mining activities and their impact on the surrounding environment have been and remain one of the major environmental impacts associated with surface mining. Dust emissions caused by the transportation ...

Du Plessis, J.J.L.; Marx, W.M.; Nell, C. (Southern African Institute of Mining and Metallurgy, 2014-12)Escalating energy and electricity costs have become one of the largest drivers of expenditure in mining operations. Over the last eight years, energy costs have tripled when expressed as a percentage of total expenses in ...

Belle, Bharath K.; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 1999-01)The project was planned in two phases. The first phase involved laboratory tests on a continuous miner model for different ventilation and spray systems at the newly built ventilation simulation tunnel at the Klopperbos ...
-
Belle, Bharath K.; Du Plessis, J.J.L.; Oberholzer, J.W. (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 ...

Biffi, Marco; Marx, Wynand; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 2006-10)The FutureMine Collaborative Research Initiative has been successfully completed after three years of activity. The main objective of this initiative was to provide applications of research previously undertaken in ...

Hood type dust control systems on continuous miner (CM) in an underground bord and pillar coal mine Belle, Bharath K.; Du Plessis, J.J.L.; Van Zyl, F.J. (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 ...

Du Plessis, J.J.L.; Potgieter, S.A.J. (Mine Ventilation Society of South Africa, 2016-07)Spotters and samplers working around surface drill rigs can be exposed to high dust concentrations. In this study it was found that individuals were exposed to as much as 14.2 mg/m3, which exceeds the Occupational ...
-
Du Plessis, J.J.L.; Scott, D.; Moorcroft, H.E.S. (Mine Ventilation Society of South Africa, 2006-07)The increasing mining depths of South African gold mine deposits are resulting in ever-increasing heat loads associated with depth and the geothermal gradient. Together with changes in the mining horizons brought about ...
-
Belle, Bharath K.; Du Plessis, J.J.L. (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 ...
-
Kleyn, G.; Du Plessis, J.J.L. (Southern African Institute of Mining and Metallurgy, 2016-04)Sub-standard practices and their adverse impact on safety performance remain a challenge in the South African gold mining industry. The purpose of this study was to investigate the root causes of sub-standard practices and ...
-
Viljoen, A.; Du Plessis, J.J.L. (Mine Ventilation Society of South Africa, 2019-01)The use of high powered catalogued auxiliary fans to meet the ventilation requirements of fairly shallow mines is common practice and often is not an energy efficient ventilation solution. This paper describes the ...

Du Plessis, J.J.L.; Van Dijk, R.L.S. (Southern African Institute of Mining and Metallurgy, 2001-10)The French research institute, INERIS, requested the assistance of the CSIR’s Division of Mining Technology in developing further precautionary measures against explosions in their collieries. In response to this approach, ...
