For centuries, denuded landscapes, fouled streams, and dirty air were accepted by society as part of the price that had to be paid for mineral production. Even initial environmental legislation devised by industrialized countries in the 1960s and 1970s was largely designed without mining in mind. And developing countries had little in the way of environmental policy. With the advent of sustainability in the 1990s, times have changed. Today's economic development, many now feel, must not come at the expense of an environmentally degraded future. Current policies toward mining are under rigorous review, and mineral-rich developing countries are designing environmental policies where none existed before. In Mining and the Environment, noted analysts offer viewpoints from Australia, Chile, the United Kingdom, the United States, and the European community on issues and challenges of metal mining.

In the past 13 years since the publication of Longwall Mining, 2nd edition in 2006, although there have been no major changes in longwall mining technology and operations, many incremental developments in the whole system as well as various subsystems of the existing longwall mining operational technologies as detailed in the 2nd edition have been added to this edition. Major developments are automation, and health and safety technology, as well as equipment reliability, thereby greatly increasing productivity and cutting cost. In particular, the longwall system can now run automatically cut by cut forever without operators' intervention provided that the geology allows it. Other health and safety features such as LASC, personal proximity detection, color lighting, automatic shield water sprays and remote shearer control are fully operational. There are more than 7000 sensors installed in current longwall mining systems. The big data obtained and fast communication technology have been fully utilized to improve and solve operational problems in real time. Those features are fully documented in the new edition. In pursuit of high productivity and cutting cost, life cycle management that increases equipment reliability has been implemented by OEM. Automation improvement such as tail-end automatic chain tensioner greatly extends AFC chain's service life. Other incremental improvements including dust and methane controls, entry development, panel design and face move are addressed. Additional operational issues such as extension of panel width and compatibility test are also discussed. Since the last plow longwall mine was closed in 2018, the chapter on plow longwalling has been dropped and in its place Automation of Longwall Components and System is added. Also, a new chapter Longwall Top Coal Caving Mining (LTCC) is added due to its successful application in Australia since 2005. Longwall Mining, 3rd edition will be of interest to professionals and academics in the field of mining engineering specifically, serving both as a reference work and an (under)graduate textbook, but will also interest civil, geomechanical and geological engineers and rock mechanics professionals, as well as coal operators, mining consultants, researchers, equipment manufacturers, and government regulators.

This wise, eloquent volume distils the essence of Dr. Jerry Lewis' rich 25-year background in the teaching of psychotherapeutic skills to residents and other professionals - skills that are central to the core identity of the psychiatrist.

An innovative study of labor relations, particularly the interactions of recruitment agents and migrant workers, in the mining concessions of Wassa, Gold Coast Colony, 1879 to 1909. Recent years have seen renewed interest in the historical study of labor in Africa. Unlike those of the past, these new studies are rooted in the recognition of Africa's dynamic, expansive, and productive informal sector. While this book focuses on one of West Africa's earliest large-scale industries, namely the Wassa gold mines in the southwest Gold Coast, it is not solely concerned with the traditional working class. Rather, it explores the plurality oflabor relations that characterized the mining concessions during the period 1879 to 1909, including the presence of migrants from various parts of West Africa as well as casual and tributary laborers, both male and female. In capturing the phenomenon of labor mobility as it played out in Wassa, Mediators, Contract Men, and Colonial Capital presents one of the fullest accounts of the labor agents who regularly brought groups of migrant laborers to the mines. The narrative discusses these agents' means of employment and roles in the informalization and indentureship of labor; in addition, it explores the regional dynamics of the recruitment machinery and confronts issues of coercion and choice. Scholars interested in African history, global labor history, economic history, and women's work in Africa will find much of value in this innovative study. Cassandra Mark-Thiesen is aResearch Fellow of the Swiss National Science Foundation (Marie-Heim Voegtlin Grant) in the history department of the University of Basel.

This book Understanding Pore Space through Log Measurements deals with porosity, insight on pore shape connectedness, grain size, grain aspect ratio, permeability etc. Most of the published literature is focused on permeability from log measurements and log analytic techniques for porosity and fluid saturation determination. On the other hand, this book aims at looking at porosity distribution, pore shape, and pore connectedness using log measurements and thus bringing pore space into focus. A compilation of available knowledge from this perspective will lead the reader to better understanding of reservoir characterization takeaways, which exploration and exploitation managers and workers will be looking for.

Innovating Construction Law: Towards the Digital Age takes a speculative look at current and emerging technologies and examines how legal practice in the construction industry can best engage with the landscape they represent. The book builds the case for a legal approach based on transparency, traceability and collaboration in order to seize the opportunities presented by technologies such as smart contracts, blockchain, artificial intelligence, big data and building information modelling. The benefits these initiatives bring to the construction sector have the potential to provide economic, societal and environmental benefits as well as reducing the incidence of disputes. The author uses a mixture of black letter law and socio-legal commentary to facilitate the discourse around procurement, law and technology. The sections of the book cover the AS IS position, the TO BE future position as predicted and the STEPS INBETWEEN, which can enable a real change in the industry. The rationale for this approach lies in ensuring that the developments are congruent with the existing frameworks provided by the law. The book proposes various steps that the industry should seriously consider taking from the current position to shape the future of the sector and ultimately create a better, more productive and sustainable construction industry. This book is a readable and engaging guide for students and practitioners looking to learn more about construction law and its relationship with technology and for those seeking a platform for graduate studies in this area.

Since 1925, import substitution programs have diverted South Africa's mineral revenues away from efficient investments and into the creation of an uncompetitive manufacturing sector. Protection has recently been augmented by a General Export Incentive Scheme that was designed to increase manufacturing exports. A multisector general equilibrium analysis shows the export scheme is highly complex with unusual and undesirable structural effects, seeming little more than a continuation of social engineering of the past. This work provides a definitive analysis of past and present South African trade policy, using a methodology of interest to other trade and development researchers operating in similarly spare informational environments.

This book offers an overview of the key debates in the burgeoning anthropological literature on resource extraction. Resources play a crucial role in the contemporary economy and society, are required in the production of a vast range of consumer products and are at the core of geopolitical strategies and environmental concerns for the future of humanity. Scholars have widely debated the economic and sociological aspects of resource management in our societies, offering interesting and useful abstractions. However, anthropologists offer different and fresh perspectives - sometimes complementary and at other times alternative to these abstractions - based on field researches conducted in close contact with those actors (individuals as well as groups and institutions) that manipulate, anticipate, fight for, or resist the extractive processes in many creative ways. Thus, while addressing questions such as: "What characterizes the anthropology of resource extraction?", "What topics in the context of resource extraction have anthropologists studied?", and "What approaches and insights have emerged from this?", this book synthesizes and analyses a range of anthropological debates about the ways in which different actors extract, use, manage, and think about resources. This comprehensive volume will serve as a key reading for scholars and students within the social sciences working on resource extraction and those with an interest in natural resources, environment, capitalism, and globalization. It will also be a useful resource for practitioners within mining and development.

Public Responses to Fossil Fuel Export provides wide-ranging theoretical and methodological international contributions on the human dimensions of fossil fuel export, with a distinctive focus on exporting countries, some of which are new entrants into the marketplace. What do members of the public think about exporting fossil fuels in places where it is happening? What do they see as its main risks and benefits? What connections are being made to climate change and the impending energy transition? How have affected communities responded to proposals related to fossil fuel export, broadly defined to include transport by rail, pipeline, and ship? Contributions to the work are presented in three parts. The first part synopsizes the background of the project, outlines major social science theories and relevant previous research, and identifies global trends in energy production. Regional and national case studies related to public opinion on fossil fuel export are included in part two of the manuscript. Part three highlights community-based case studies. Implications for research and practice feature in the concluding chapter.

Providing a holistic understanding of extensive oil extraction in rural Mexico, this book focuses on a campesino community, where oil extraction is deeply inscribed into the daily lives of the community members. The book shows how oil shapes the space where it is extracted in every aspect and produces multiple uncertainties. The community members express these uncertainties using the metaphor of the time bomb. The book shows how they find ways to "live off the time bomb" by using mechanisms of short-term coping and long-term adaptation and thus, developing the capability to determine their lives despite the ever-changing challenges.

This book is a novel contribution to a field dominated by conventional approaches to project management, it is about narratives in megaprojects. Some of the questions examined in this original new book include: * What are narratives? * Why are they important in megaprojects? * How are they formed and used in megaprojects? * How do promotors of and protestors against megaprojects craft narratives to their advantage? * What strategies can project managers employ to effectively use narratives in megaprojects? Built from longitudinal research studies in combination with internationally recognised teaching materials, this book will provide readers with a theoretical understanding of narratives and projects, as well as practical international case studies, including HS2, the Eden Project, the Sochi Olympics, Hyderabad and Chennai Metros, Westconnex and Tideway, to support their understanding. The authors explain the different types of narrative, how and why they are important in general and in relation to a megaproject and its life-cycle, but also how to craft narratives in different situations, and how they are changed and maintained over a project life-cycle. Narratives in Megaprojects doubles as a text supporting more advanced courses on project management or aspects thereof, and as a reflection of the state of the art in this particular perspective on megaprojects. It is essential reading for all students and professionals in Project Management, Construction, Infrastructure and Executive Leaders involved in megaprojects and infrastructure delivery.

This book develops a discursive 'equalitarian' theoretical framework for studying African mining ecosystem issues and policy interventions. The theory of 'equalitarianism' is developed as an alternative to the reductionist approach that has dominated post-colonial debates about the classical jus ad bellum requirements to empower women in development spaces. However, the classical approach narrows the debate down to "women issues," rather than the 'whole-of-society.' As a consequence of this reductionism, women continue to be devalued in the mining sector, characterized by poverty traps, power struggles, and a lack of capacity to engage in large-scale mining (LSM) activities. This book advances principles for a holistic approach, and spells out the implications for women across the mining value chain. Drawing on moral scholarship, the book poses that for women to gain access to strategic spaces in the mining sector, the drive for empowerment must be embedded within 'whole-of-society' principles. This book is of interest to scholars researching gender policy, public policy, political philosophy, conflictology, and human geography. It also offers practitioners a guide for evaluating their policy work on mainstreaming gender in the mining sector, presenting options for financing, forging partnership and planning for an inclusive economic development in Africa, and beyond.

A Practical Guide to Piping and Valves for the Oil and Gas Industry covers how to select, test and maintain the right oil and gas valve. Each chapter focuses on a specific type of valve with a built-in structured table on valve selection. Covering both onshore and offshore projects, the book also gives an introduction to the most common types of corrosion in the oil and gas industry, including CO2, H2S, pitting, crevice, and more. A model to evaluate CO2 corrosion rate on carbon steel piping is introduced, along with discussions on bulk piping components, including fittings, gaskets, piping and flanges. Rounding out with chapters devoted to valve preservation to protect against harmful environments and factory acceptance testing, this book gives engineers and managers a much-needed tool to better understand today's valve technology.

The mining industry faces distinct challenges. Mines have long lives, companies have little control over the prices at which they sell, prices are volatile, and the environmental impacts of mining are often not well managed. Despite this, the mining industry has received relatively little attention from neither economists nor the wider business community. There is a need to address the unique management challenges raised by this globally important industry. Modern Management in the Global Mining Industry addresses the economics of mining industries and the management of global mining companies in a manner which is both practical and guided by economic and management theory. Leading with the assertion that mining generates substantial benefits for all its stakeholders provided it is well-managed, and that this includes management of environmental impacts, the book argues that mining companies should move to seeing environmental preservation and sustenance of local communities as an objective rather than a constraint. The book will be an important reference for practitioners working in mining and related industries and to researchers of economic and management theory, mining operations, mining engineering and commodities.
