Rockburst: Mechanisms, Monitoring, Warning and Mitigation invites the most relevant researchers and practitioners worldwide to discuss the rock mechanics phenomenon related to increased stress and energy levels in intact rock introduced by drilling, explosion, blasting and other activities. When critical energy levels are reached, rockbursts can occur causing human and material losses in mining and tunneling environments. This book is the most comprehensive information source in English to cover rockbursts. Comprised of four main parts, the book covers in detail the theoretical concepts related to rockbursts, and introduces the current computational modeling techniques and laboratory tests available. The second part is devoted to case studies in mining (coal and metal) and tunneling environments worldwide. The third part covers the most recent advances in measurement and monitoring. Special focus is given to the interpretation of signals and reliability of systems. The following part addresses warning and risk mitigation through the proposition of a single risk assessment index and a comprehensive warning index to portray the stress status of the rock and a successful case study. The final part of the book discusses mitigation including best practices for distressing and efficiently supporting rock. Designed to provide the most comprehensive coverage, the book will provide practicing mining and tunneling engineers the theoretical background needed to better cope with the phenomenon, practical advice from case studies and practical mitigation actions and techniques. Academics in rock mechanics will appreciate this complete reference to rockburst, which features how to analyze stress signals and use computational modeling more efficiently. - Offers understanding of the fundamental theoretical concepts of rockbursts - Explores how to analyze signals from current monitoring systems - Shows how to apply mitigating techniques in current work - Identifies characteristics that should be measured in order to detect rockburst risk

First published in 1983, this book provides a comprehensive view of gold and gold trading in its many facets, and identifies those sources of information that are important for an understanding of the world’s gold markets. The author looks first at gold’s changing role since 1960; in particular, the change from the fixed price to the present free market determination of price. The different forms the demand for gold takes – bullion, paper or in fabricated forms such as jewellery – are explained in detail. This is followed by an analysis of the supply side – new gold production and the circulation of existing old gold. The survey concludes with an assessment of the gold market and of gold prices now and in the future.

Before the advent of the great mineral revolution in the latter half of the 19th century, South Africa was a sleepy colonial backwater whose unpromising landscape was seemingly devoid of any economic potential. Yet lying just beneath the dusty surface of the land lay the richest treasure trove of gold, diamonds, platinum, coal and a host of other metals and minerals that has ever been discovered in one country. It was the discovery and exploitation of first diamonds in 1870 and then gold in 1886 that proved the catalyst to the greatest mineral revolution the world has ever known, which transformed South Africa into the supreme industrialised power on the African continent. Here for the first time is the complete history of South Africa's phenomenal mineral revolution spanning a period of more than 150 years, from its earliest commercial beginnings to the present day, incorporating seven of the major commodities that have been exploited. Digging Deep describes the establishment and unparalleled growth of mining, tracing the history of the industry from its humble beginnings where copper was first mined on a commercial basis in Namaqualand in the Cape Colony in the early 1850s, to the discovery and exploitation of the country's other major mineral commodities. This is also the story of how mining gave rise to modern South Africa and how it compelled the country to develop and progress the way in which it did. It also incorporates the stories of the visionary men - Cecil Rhodes, Alfred Beit, Barney Barnato, Sir Ernest Oppenheimer, Sammy Marks and Hans Merensky - who pioneered and shaped the development of the industry on which modern South Africa was built.

As late as the beginning of the nineteenth century, despite the many years of direct contact with European traders and the influx of European goods, most African societies still produced their own iron and its products, or obtained them from neighbouring communities through local trade. The quality of iron products was such that, despite competition from European imports, local iron production survived into the early twentieth century in some parts of the continent. The production process covered prospecting, mining, smelting, and forging. Different types of ore were available all over the continent and were extracted by shallow or alluvial mining. A variety of skills were required for building furnaces, producing charcoal, smelting, and forging iron into goods. Iron production was generally not an enclave activity but a process that fulfilled the totality of socio-economic needs. It also fit the gender division of labour within communities.

Increasingly stringent environmental regulations and industry adoption of waste minimization guidelines have thus, stimulated the need for the development of recycling and reuse options for metal related waste. This book, therefore, gives an overview of the waste generation, recycle and reuse along the mining, beneficiation, extraction, manufacturing and post-consumer value chain. This book reviews current status and future trends in the recycling and reuse of mineral and metal waste and also details the policy and legislation regarding the waste management, health and environmental impacts in the mining, beneficiation, metal extraction and manufacturing processes. This book is a useful reference for engineers and researchers in industry, policymakers and legislators in governance, and academics on the current status and future trends in the recycling and reuse of mineral and metal waste. Some of the key features of the book are as follows: Holistic approach to waste generation, recycling and reuse along the minerals and metals extraction. Detailed overview of metallurgical waste generation. Practical examples with complete flow sheets, techniques and interventions on waste management. Integrates the technical issues related to efficient resources utilization with the policy and regulatory framework. Novel approach to addressing future commodity shortages.
