Around the world, large-scale metals mining takes an enormous toll on the health of the environment and communities. Gold mining, in particular, is one of the dirtiest industries in the world. Massive open-pit mines, some measuring as much as two miles (3.2 kilometers) across, generate staggering quantities of waste—an average of 76 tons for every ounce of gold.1 In the US, metals mining is the leading contributor of toxic emissions to the environment.2 And in countries such as Ghana, Romania, and the Philippines, mining has also been associated with human rights violations, the displacement of people from their homes, and the disruption of traditional livelihoods.

  • How Understanding a Railway's Historic Evolution Can Guide Future
    College of Engineering, School of Civil Engineering University of Birmingham Managing Technical and Operational Change: How understanding a railway’s historic evolution can guide future development: A London Underground case study. by Piers Connor Submitted as his PhD Thesis DATE: 15th February 2017 University of Birmingham Research Archive e-theses repository This unpublished thesis/dissertation is copyright of the author and/or third parties.

Managing Technical & Operational Development PhD Thesis Abstract The argument for this thesis is that patterns of past engineering and operational development can be used to support the creation of a good, robust strategy for future development and that, in order to achieve this, a corporate understanding of the history of the engineering, operational and organisational changes in the business is essential for any evolving railway undertaking. It has been the objective of the author of this study to determine whether it is essential that the history and development of a railway undertaking be known and understood by its management and staff in order for the railway to function in an efficient manner and for it to be able to develop robust and appropriate improvement strategies in a cost-effective manner.

  • Reef Adjacent to Structures at Tautona Mine, Anglogold Ashanti South African Operations
    Reef Adjacent To Structures at TauTona Mine, AngloGold Ashanti South African Operations DE DAVIES Section Manager TauTona Mine, AngloGold Ashanti South African Operations SYNOPSIS The paper describes the extraction of reef adjacent to geological structures in the Carbon Leader Reef Section at TauTona Mine. Traditionally long wall mining has left feasible and economical blocks of ground adjacent to structures when negotiating major geological features. This meant that mining through an up- throw fault, rolling to the reef elevation on the displaced side of the fault left reef in the long wall. High grade areas were abandoned and gold was sterilized. In these tight economic times and with the need to continuously improve safety standards the need arose to develop a technique to extract these blocks economically and safely. It was believed that the structures in these abandoned areas were de-stressed and could now be mined in small volumes at a high grade. The term RATS is an acronym derived from “reef adjacent to structures” and aptly describes the process of identifying and extracting these blocks. The viability of this method was addressed in terms of the mine design, underground investigations and financial risks. The paper concludes with an analysis of the successes achieved to date. 1 INTRODUCTION TauTona Mine is one of the AngloGold Ashanti Southern Africa operations. It is close to the town of Carletonville in the province of Gauteng and about 70km south-west of Johannesburg. TauTona is 46 years old and employs ± 4 000 people. Mining operations are conducted at depths ranging from 1,800m to 3,500m at which the world’s deepest stoping sections are found.
