(University of Pretoria, 1997)The N.N.W.-S.S.E. striking Rustenburg Fault zone, in the western Transvaal Basin, South Africa, has been mapped, in order to unravel its tectonic history. Thickness differences in the Daspoort Formation of the Pretoria ...
-
(University of Pretoria, 1998)Premier Diamond mine had to plan, develop and operate a low cost, mass mining method to recover extensive ore reserves below a 75 metre thick, dipping gabbro sill. The mining method had to preclude the extraction of as ...
-
(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 ...
-
(Southern African Institute of Mining and Metallurgy, 1999-05)Please read abstract in article.
-
(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 ...
-
(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, ...
-
(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 ...
-
(University of Pretoria, 2005-03-31)The mine planning process converts resources into economically mineable reserves, focusing on value addition and risk reduction. Equipment selection is traditionally addressed late in the process and addresses production ...
-
(University of Pretoria, 2006-05-19)The study that is described in this thesis deals with stope support design from a rockmass stiffness approach. Three models were developed and combined into a single one in the third part of the study in an attempt to ...
-
(University of Pretoria, 2006-06-07)Instability in stope panels in shallow mines manifests itself as rockfalls from the hangingwall. Rockfalls from unstable stope panels vary in size from rockfalls between support units, to rockfalls spanning between pillars ...
-
(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 ...
-
(University of Pretoria, 2006-07-20)The testing undertaken for this dissertation is intended to help quantify the various time-dependant deformation processes around typical deep level hard rock tabular excavations. Three mechanisms were investigated and two ...
-
(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 ...
-
(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 ...
-
(University of Pretoria, 2007-03-05)Please read the abstract in the 00front part of this document
-
(University of Pretoria, 2007-07-24)In this thesis a previously unknown mechanism of failure in multilayered slope profiles is identified. In some conditions this mechanism does not confirm to the known failure models (relating to circular failure) used in ...
-
Determining the physical and economic impact of environmental design criteria for ultra-deep mines (University of Pretoria, 2007-07-24)Please read the abstract in the section 00front of this document
