The contributions in this book were presented at the workshop Measurement and Analysis of Blast Fragmentation, which was hosted by Fragblast 10 (New Delhi, India, November 2012), provide a snapshot of the activity in rock fragmentation measurements and analysis around the world, and are a must-have reference for engineers and researchers working in rock blasting.
Underground geological storage of carbon dioxide (CO2) has considerable potential for mitigating climate change. CO2 can be safely injected and stored at well characterized and properly managed sites. Injecting carbon dioxide in deep geological formations can store it underground for long periods of time. Depleted oil and gas reservoirs, saline aquifers and carboniferous formations can be used for storage of CO2, as well as in abandoned coal mines. At depths below about 800-1000m, CO2 has a liquid-like density that permits the efficient use of underground reservoirs in porous sedimentary rocks. The papers in the present volume are from leading experts in the field of CO2 storage and were presented at an International Workshop on CO2 Storage in Carboniferous Formations and Abandoned Coal Mines (Beijing, China, 8-9 January 2011). CO2 storage in abandoned coal mines appears to have a bright future. Although CO2 Storage in Carboniferous Formations and Abandoned Coal Mines is primarily intended for mining engineers, environmental engineers and engineering geologists, the book will also be useful to civil engineers, and academics and professionals in geophysics and geochemistry.
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.

Solutions for soil engineering and soil-structure interaction problems need realistic and pertinent experimental and modelling tools. In this work, extensive developments proposed by the invited speakers of the Lyon International Symposium held in September 2003 are presented, including experimental investigations into deformation properties; laboratory, in-situ and field observation interpretations; behaviour characterisation and modelling; and case histories. The contributions include recent investigations into anisotropy and non-linearity, the effects of stress-strain-time history, ageing and time effects, yielding, failure and flow, cyclic and dynamic behaviour. In addition, advanced geotechnical testing is applied to real engineering problems, and to ways of synthesising information from a range of sources while engaging in practical site characterisation studies.
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.
The purpose of this book is to examine both the positive and negative socioeconomic impacts of artisanal and small-scale mining in developing countries. In recent years, a number of governments have attempted to formalize this rudimentary sector of industry, recognizing its socioeconomic importance. However, the industry continues to be plagued by a wide range of problems, including environmental and health-related impacts, rampant illegal activity and illicit mineral marketing, and disease. The book provides an up-to-date overview of social and economic conditions in the artisanal and small-scale mining industry, integrating both theoretical assessments with case study research recently undertaken in the field. It features the following five sections: Policy and Regulatory Issues in the Small-Scale Mining Industry; Artisanal and Small-Scale Mining, Labour and the Community; African Case Studies of Artisanal and Small-Scale Mining; Asian Case Studies of Artisanal and Small-Scale Mining; and Latin American Case Studies of Artisanal and Small-Scale Mining. Geared toward servicing a wide-ranging audience, including academics, consultants, and government researchers, The Socioeconomic Impacts of Artisanal and Small-Scale Mining in Developing Countries is an invaluable tool for policy-makers at all levels.

This book covers a wide range of topics relating to the health and wellbeing of the construction workforce. Based on more than a decade of work examining various aspects of workers' health and wellbeing, the book addresses a key topic in construction management: how the design of work environments, construction processes and organisation of work impact upon construction workers' physical and psychological health. Occupational health is a significant problem for the construction industry. However, the subject of health is usually treated as an afterthought in other books which emphasise safety issues. Traditional management approaches (focused on the prevention of accidents and injuries) are arguably ill-suited to addressing issues of workers' health and wellbeing. The evidenced informed approach in this book provides a rich analysis of how construction workers' health and wellbeing are impacted by working in the construction industry, and critical information about how organisations (and decision-makers within them) can create workplaces and practices that are supportive and enable construction workers to maintain healthy and productive working lives. Including chapter summaries and discussion questions to encourage student readers to reflect on and formulate their own viewpoints about the issues raised in each chapter, the book has the potential to be used as a textbook in undergraduate or postgraduate occupational health and safety, or construction management courses dealing with occupational health and safety. It could also be used as supplementary, recommended reading in undergraduate or postgraduate programs in architecture, engineering or management.

In the story of the The Golden Republic, Bulpin sets a stage on which we meet some of the strangest characters that fate had ever attached to the puppet strings of destiny. The grim Mzilikazi; the hot-headed Hendrik Potgieter and his trekkers; prospectors like Charlie the Reefer; gaudy rogues like Gunn of Gunn and his Highlanders; bandits, highwaymen, rand lords, gold rushers, to name just a few. He tells of leaders like Pretorius and Kruger, and many others who each played a part in establishing the Republic of the Transvaal – a seemingly impossible task considering all the small wars and skirmishes on the veld and the rumble of arguments rising out of each farmhouse. In his remarkably engaging style of writing he sketches scenes of rough but beautiful land, which must have been fascinating to explorers who roamed about the old Transvaal with all its scenic novelties where every turn yielded some marvel for the geologist, the botanist, or the zoologist. The Golden Republic tells of the adventure that raised the Republic to its peak and the complex intrigues that brought it down to the dust; of misfortune and riches, and despair of such magnitude that the birth of a Republic seemed inevitable considering the economic disaster it at times experienced … Until gold poked out its shiny head and gave hope again. The characters who crowded into diggers’ towns were some of the wildest and most colourful ever known in the Transvaal. From all over South Africa they flocked to the scene, in the hope of finding fortune. Most of them were just opportunists, who knew nothing about gold except how to spend it. This is a brilliant book of the birth, life and death of the old Republic written in the tell-tale style Bulpin does so well.
This book explores the challenges and opportunities at the intersection of the global mining sector and local communities by focusing on a number of international cases drawn from various locations in Canada, the Philippines and Scandinavia. Mining's contribution to economic development varies greatly across countries. In some, it has been a major engine of development, but in others, disputes have erupted over land use, property rights, environmental damage, and revenue sharing. Corporate social responsibility programs are increasingly relied upon to manage company-community relations, yet conflicts persist in many settings, with significant costs for companies and communities. Exploring the many factors and drivers that characterise relationships among different actors within the sector, the volume contributes towards the development of practical wisdom, collective understanding, common sense, and prudence required for the mining sector and community partners to realize the economic potential and social and environmental responsibilities of non-renewable resource development. The book examines case studies from Canada, Scandinavia and the Philippines, three regions amongst the world's top countries of mining operations. Drawing on their extensive experience in these regions, the contributors explore distinctive mining sectors in the Global North and South, the variation surrounding different types of extractive industries, and at different scales, and the legal processes in place to protect local communities. Key themes include corporate social responsibility, impact assessment, foreign ownership, Indigenous Peoples, gender, local insurgency and mining disasters as well as climate change. The book identifies areas of future research and pathways to achieving stronger, respectful and mutually beneficial relationships at the nexus of global mineral extraction and local communities. This book will be of great interest to students and scholars of the extractive industries, natural resource management, sustainable business and corporate social responsibility, Indigenous studies, and sustainable planning and development.
