Blasting practices in mines have undergone many changes in the recent past and continue to be honed and reconfigured to meet the demands of today's mining needs. This volume compiles papers of the workshop Blasting in Mines - New Trends, hosted by the Fragblast 10 Symposium . The 17 papers provide a mix which highlight the evolving trends in blasting in mines. These range from special techniques of cast blasting, applications of seed wave modelling for improved fragmentation, to design of mass blasts and controlled blasting for stability of pit-walls. Blasting in Mines - New Trends will be of particular interest to mining and blasting engineers.

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.

An oral history of the West Virginia Mine Wars published to coincide with the centennial of the Battle of Blair Mountain. In 1972 Anne Lawrence came to West Virginia at the invitation of the Miners for Democracy movement to conduct interviews with participants in, and observers of, the Battle of Blair Mountain and other Appalachian mine wars of the 1920s and '30s. The set of oral histories she collected-the only document of its kind-circulated for many years as an informal typescript volume, acquiring an almost legendary status among those intrigued by the subject. Key selections from it appear here for the first time as a published book, supplemented with introductory material, maps, and photographs. The volume's vivid, conversational mode invites readers into miners' lived experiences and helps us understand why they took up arms to fight anti-union forces in some of the nation's largest labor uprisings. Published to coincide with the celebration of the Blair Mountain centennial in 2021, On Dark and Bloody Ground includes a preface by public historian Catherine Venable Moore and an afterword by Cecil E. Roberts of the United Mine Workers of America.

Fine Reservoir Description: Techniques, Current Status, Challenges and Solutions presents studies on fine oil and gas reservoirs, covering aspects of current status and progress, content and methods/techniques, as well as challenges and solutions through literature review and case studies of reservoirs, including volcanic rocks in the Songliao Basin, glutenite at the northwestern margin of the Junggar Basin, and sandstone in the Liaohe Basin, China. This book contains a large amount of data and illustrations.

Drawing on the latest archaeological discoveries, sampling techniques, and laboratory investigations, this book provides a comprehensive history of the development of extractive metallurgy.

This richly-illustrated reference guide presents innovative techniques focused on reducing time, cost and risk in the construction and maintenance of underground facilities:

A primary focus of the technological development in underground engineering is to ease the practical execution and to reduce time, cost and risk in the construction and maintenance of underground facilities such as tunnels and caverns. This can be realized by new design tools for designers, by instant data access for engineers, by virtual prototyping and training for manufacturers, and by robotic devices for maintenance and repair for operators and many more advances.

This volume presents the latest technological innovations in underground design, construction, and operation, and comprehensively discusses developments in ground improvement, simulation, process integration, safety, monitoring, environmental impact, equipment, boring and cutting, personnel training, materials, robotics and more. These new features are the result of a big research project on underground engineering, which has involved many players in the discipline.

Written in an accessible style and with a focus on applied engineering, this book is aimed at a readership of engineers, consultants, contractors, operators, researchers, manufacturers, suppliers and clients in the underground engineering business. It may moreover be used as educational material for advanced courses in tunnelling and underground construction.

Why did South African mines become renowned for mine safety, while the mounting rate of silicosis in black migrant workers lay hidden for over a century? How complicit were regulating officers in the operation of the gold mines' apartheid health and safety policies? Why and how was tuberculosis among black migrant miners not disclosed, perpetuating a cycle of disease (and death) and allowing the infection to spread to neighbouring states? This book reveals how the South African mining industry, abetted by a minority state, hid a pandemic of silicosis for almost a century, and allowed workers infected with tuberculosis to spread the potentially fatal disease to rural communities in South Africa and labour-sending states. The first crisis of 1896-1912 focused on the minority white workers and resulted in industry investing heavily on reducing dust levels. The second began in 2000 with mounting scientific evidence that the disease rate among black migrant miners is more than a hundred times higher than officially acknowledged. This has resulted in class actions against operating companies.

South Africa's prosperity was built on the wealth dragged out of the ground by mine workers: the first volume of three runs up to the defeat of the mineworkers' strike in 1946 and the election of the first Nationalist Party government. Key Features include: Information on the early days of the industry from slavery to compound labour. Explanation of the coercive forces that drove workers to the mines and of the creation of a permanent supply of cheap black labour. Strikes and Protests from the 1920s to 1946

The International Mining Forum is a recurring event, hosted by the University of Science and Technology in Cracow, Poland, bringing together an international group of scientists, including those working in rock mechanics and computer engineering as well as mining engineers. The topics are wide-ranging, including papers on remote sensing to assess primary impact; treatment of sealed-off coal mine fires; sustainable development in mine closure; and monitoring of natural hazards and safety issues.

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.

Key Features: Describes feedstock evaluation and the effects of elemental, chemical and fractional composition. Details reactor types and bed types. Explores the process options and parameters involved. Assesses coke formation and additives. Considers next generation processes and developments.

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.

Overseas Press Club Award Winner 2016 A shocking investigative journey into the way the resource trade wreaks havoc on Africa, 'The Looting Machine' explores the dark underbelly of the global economy. 'The Looting Machine' is a searing expose of the global web of traders, bankers, middlemen, despots and corporate raiders that is pillaging Africa's vast natural wealth. From the killing fields of Congo to the crude-slicked creeks of Nigeria, a great endowment of oil, diamonds, copper, iron, gold and coltan has become a curse that condemns millions to poverty, violence and oppression. That curse is no accident. This gripping investigative journey takes us into the shadows of the world economy, where secretive networks conspire with Africa's kleptocrats to bleed the continent dry. And like their victims, the beneficiaries of this grand looting have names.

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.

The Joint 6th Biennial SGA-SEG Meeting was held in Krakow in August 2001. This volume contains 274 extended abstracts, grouped thematically under 18 session titles covering topics such as lead-zinc deposits; metamorphism affecting mineral deposits; and the environmental aspects of mining.

This text covers the use of computer applications in the mineral industries, encompassing topics such as the use of computer visualization in mining systems and aspects such as ventilation and safety.

First published in 2000. Routledge is an imprint of Taylor & Francis, an informa company.

This text looks at mine planning and equipment and covers topics such as: design and planning of surface and underground mines; geotechnical stability in surface and underground mines; and mining and the environment.

The taxation of extractive industries exploiting oil, gas, or minerals is usually treated as a sovereign, national policy and administration issue.This book offers a uniquely comprehensive overview of the theory and practice involved in designing policies on the international aspects of fiscal regimes for these industries, with a particular focus on developing and emerging economies.

International Taxation and the Extractive Industries addresses key topics that are not frequently covered in the literature, such as the geo-political implications of cross-border pipelines and the legal implications of mining contracts and regional financial obligations. The contributors, all of whom are leading researchers with experience of working with governments and companies on these issues, present an authoritative collection of chapters. The volume reviews international tax rules, covering both developments in the G20-OECD project on ’Base Erosion and Profit Shifting’ and more radical proposals, identifying core challenges in the extractives sector.

This book should become a core resource for both scholars and practitioners. It will also appeal to those interested in international tax issues more widely and those who study environmental economics, macroeconomics and development economics.

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.
