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, 2014-01)Mining is a hugely expensive process and unlike manufacturing is based on an ever diminishing resource. It requires a continuous infusion of capital to sustain production. A myriad of factors, from the volatility of the ...
-
(University of Pretoria, 2016)The purpose of this research is to formulate mathematical models for assisting the management of either a new or operating surface coal mine to assess its competitiveness relative to other coal producers for a given market ...
-
(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, 2016)The global mining industry is currently under pressure. The industry is in the midst of the largest mining super cycle since the Second World War. Mining companies face increasing challenges to profitability due to ...
-
(University of Pretoria, 2007-07-30)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2023)The value of digital information is ever-increasing as more companies utilize digital technologies such as Artificial Intelligence (AI) and the Internet of Things (IoT) to gain deeper insight into their business operations ...
-
(University of Pretoria, 2015)In coal mining, spontaneous combustion can occur in many areas such as stockpiles, underground workings, waste dumps, coal faces, in-pit ramps and backfill areas. Spontaneous combustion has been defined as an oxidation ...
-
(University of Pretoria, 2017)A conceptual study is regarded as the first phase in the development of a new open pit mine. The phased approach (conceptual, prefeasibility, feasibility) is described as a “stepwise risk reduction” process, whereby each ...
-
(University of Pretoria, 2013)This study investigated different underground bulk air heat exchanger (>100 m3/s) design criteria. It was found that no single document exist covering these heat exchangers and therefore the need was identified to generate ...
-
(University of Pretoria, 2015)Crush pillars are used as part of the stope support in intermediate depth tabular mining stopes. Crush pillar design should ensure that the pillars crush when formed at the mining face. This behaviour of the pillars is ...
-
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
-
(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 ...
-
(University of Pretoria, 2009-12-09)The ability of an explosive to break rock is influenced considerably by the extent of confinement in the blasthole and it is believed that confinement is improved by the use of stemming. The aim of this paper is to present ...
-
(University of Pretoria, 2007-11-09)In general, as the uniaxial compressive strength of rock samples is tested, the uniaxial strength of the rock decreases with increasing sample size until a strength is reached beyond which no further decrease in strength ...
-
(University of Pretoria, 2015)In mining, the loading environment on pillars is highly complex with combinations of normal and shear stresses. It is also understood that with an active and working face, constant redistribution of stresses will occur to ...
-
(University of Pretoria, 2014)This document describes the re-engineering principles applied in the design of a personnel transportation system for a platinum mine in the Rustenburg area of South Africa. It incorporates conveyor belt travelling, chairlift ...
-
(University of Pretoria, 2008-08-06)This thesis addresses the problem of designing roof support systems in coal mines. When designing the roof support, it is necessary to account for the uncertainties that are inherently exist within the rock mass and support ...
-
(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 ...
