-
(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, 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, 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 ...
-
Structural mechanisms contributing to large-scale hangingwall instabilities on the UG2 reef horizon (University of Pretoria, 2019)Structural complexities, including regional geologic structures, low-angle structures, ramp structures and alteration zones contribute towards large-scale hangingwall or structural (pillar) instabilities experienced in ...

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, 2018)In the past decades, attempts were made to build a systematic approach to mining method selection (MMS) Ooriad et al, (2018). This is because MMS is a complex and irreversible process. Since it can affect the economic ...
-
(University of Pretoria, 2018)The process of mining is about executing a few, seemingly easy, routine activities with consistency and precision over an extended period of time. The research that has been conducted during the course of this study has ...
-
(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, 2016)In recent years, innovation in the mining industry has shifted from being a non-essential business activity to a necessity. Key challenges in the last decade (such as declining ore grades and increased mining costs) have ...
-
(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, 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 ...
-
(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, 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, 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 ...
-
(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, 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, 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, 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 ...
