This book teaches readers ground engineering principles and related mining and risk management practices associated with underground coal mining. It establishes the basic elements of risk management and the fundamental principles of ground behaviour and then applies these to the essential building blocks of any underground coal mining system, comprising excavations, pillars, and interactions between workings. Readers will also learn about types of ground support and reinforcement systems and their operating mechanisms. These elements provide the platform whereby the principles can be applied to mining practice and risk management, directed primarily to bord and pillar mining, pillar extraction, longwall mining, sub-surface and surface subsidence, and operational hazards. The text concludes by presenting the framework of risk-based ground control management systems for achieving safe workplaces and efficient mining operations. In addition, a comprehensive reference list provides additional sources of information on the subject. Throughout, a large variety of examples show good and bad mining situations in order to demonstrate the application, or absence, of the established principles in practice. Written by an expert in underground coal mining and risk management, this book will help students and practitioners gain a deep understanding of the basic principles behind designing and conducting mining operations that are safe, efficient, and economically viable.

The flooding and subsequent closure of Scotland's last deep coal mine in 2002 brought a centuries long saga to an end. Villages and towns across the densely populated Central Belt owe their existence to coal mining's expansion during the nineteenth century and its maturation in the twentieth. Colliery closures and job losses were not just experienced in economic terms: they had profound implications for what it meant to be a worker, a Scot and a resident of an industrial settlement. Coal Country presents the first book-length account of deindustrialization in the Scottish coalfields. It draws on archival research using records from UK government, the nationalized coal industry and trade unions, as well as the words and memories of former miners, their wives and children that were collected in an extensive oral history project. Deindustrialization progressed as a slow but powerful march across the second half of the twentieth century. In this book, big changes in cultural identities are explained as the outcome of long-term economic developments. The oral testimonies bring to life transformations in gender relations and distinct generational workplaces experiences. This book argues that major alterations to the politics of class and nationhood have their origins in deindustrialization. The adverse effects of UK government policy, and centralization in the nationalized coal industry, encouraged miners and their trade union to voice their grievances in the language of Scottish national sovereignty. These efforts established a distinctive Scottish national coalfield community and laid the foundations for a devolved Scottish Parliament. Coal Country explains the deep roots of economic changes and their political reverberations, which continue to be felt as we debate another major change in energy sources during the 2020s.
Coal mining continues to make advances, especially in the areas of safety and environmental protection as a result of mining. This book contains nine peer-reviewed articles on green coal mining that address most of the important issues associated with improving coal mining. These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.
Advanced Mine Ventilation presents the reader with a unique book providing the theory and applications for designing mine ventilation with computers, controlling respirable coal dust and diesel particulate matter, combustible gas control and, mine fire management. The book summarizes the latest knowledge created in the past 40 years in these areas. Authored by an expert in the field with 50 years' experience, the book is a great combination of theory and applications. The mine ventilation section provides computer programs (both FORTRAN and C++) to calculate not only air quantities and pressure losses but also the concentration of any pollutant in all junctions and branches of the mine network. Small particle mechanics and dust control is covered in the second section of the book. The third section on combustible gas control discusses all aspects of mine gases from origin to control. The last section on mine fire control discusses spontaneous combustion, frictional ignitions, mine explosions, and mine sealing and recovery. The book is not only a very good reference book but also an excellent textbook for two graduate level courses in Mining Engineering. - Provides the latest knowledge on the four related topics of mine environment control; that is, ventilation, dust, gas, and fire in a single volume - Computer simulation of mine ventilation in both FORTRAN and C++ - State-of-the-art respirable dust control - Mine degasification and methane production from a coal lease - Mine fire management

In a devastating and urgent work of investigative journalism, Pulitzer Prize winner Chris Hamby uncovers the tragic resurgence of black lung disease in Appalachia, its Big Coal cover-up, and the resilient mining communities who refuse to back down. Decades ago, a grassroots uprising forced Congress to enact long-overdue legislation designed to virtually eradicate black lung disease and provide fair compensation to coal miners stricken with the illness. Today, however, both promises remain unfulfilled. Levels of disease have surged, the old scourge has taken an aggressive new form, and ailing miners and widows have been left behind by a dizzying legal system, denied even modest payments and medical care. In this devastating and urgent work of investigative journalism, Pulitzer Prize winner Chris Hamby traces the unforgettable story of how these trends converge in the lives of two men: Gary Fox, a black lung-stricken West Virginia coal miner determined to raise his family from poverty, and John Cline, an idealistic carpenter and rural medical clinic worker who becomes a lawyer in his fifties. Opposing them are the lawyers at the coal industry’s go-to law firm; well-credentialed doctors who often weigh in for the defense, including a group of radiologists at Johns Hopkins; and Gary’s former employer, Massey Energy, the region’s largest coal company, run by a cantankerous CEO often portrayed in the media as a dark lord of the coalfields. On the line in Gary and John’s longshot legal battle are fundamental principles of fairness and justice, with consequences for miners and their loved ones throughout the nation. Taking readers inside courtrooms, hospitals, homes tucked in Appalachian hollows, and dusty mine tunnels, Hamby exposes how coal companies have not only continually flouted a law meant to protect miners from deadly amounts of dust but also enlisted well-credentialed doctors and lawyers to help systematically deny much-needed benefits to miners. The result is a legal and medical thriller that brilliantly illuminates how a band of laborers — aided by a small group of lawyers, doctors and lay advocates, often working out of their homes or in rural clinics and tiny offices – challenged one of the world's most powerful forces, Big Coal, and won. A deeply troubling yet ultimately triumphant work, Soul Full of Coal Dust is a necessary and timely book about injustice and resistance.

Mark Twain observed, “I'm in favour of progress; it's change I don't like.” Coal dominates Indian energy because it’s available domestically and cheap (especially without a carbon tax). If the global focus is on the energy transition, how does India ensure a just transition? Managing winners and losers will be the single largest challenge for India’s energy policy. Coal is entrenched in a complex ecosystem. In some states, it’s amongst the largest contributors to state budgets. The Indian Railways, India’s largest civilian employer, is afloat because it overcharges coal to offset under-recovery from passengers. Coal India Limited, the public sector miner that produces 85% of domestic coal, is the world’s largest coal miner. But despite enormous reserves, India imports about a quarter of consumption. On the flip side, coal faces inevitable pressure from renewable energy, which is the cheapest option for new builds. However, there is significant coal-based power capacity already in place, some of which is underutilized, or even stranded. Low per-capita energy consumption means India must still grow its energy supply. Before India can phase out coal, it must first achieve a plateau of coal. How this happens cost-effectively and with least resistance isn’t just a technical or economic question, it depends on the political economy of coal and its alternatives. Some stakeholders want to kill coal. A wiser option may be to first clean it up, instead of wishing it away. Across 18 chapters, drawing from leading experts in the field, we examine all aspects of coal’s future in India. We find no easy answers, but attempt to combine the big picture with details, bringing them together to offer a range of policy options.
Employment and production in the Appalachian coal industry have plummeted over recent decades. But the lethal black lung disease, once thought to be near-eliminated, affects miners at rates never before recorded. Digging Our Own Graves sets this epidemic in the context of the brutal assault, begun in the 1980s and continued since, on the United Mine Workers of America and the collective power of rank-and-file coal miners in the heart of the Appalachian coalfields. This destruction of militancy and working class power reveals the unacknowledged social and political roots of a health crisis that is still barely acknowledged by the state and coal industry. Barbara Ellen Smith’s essential study, now with an updated introduction and conclusion, charts the struggles of miners and their families from the birth of the Black Lung Movement in 1968 to the present-day importance of demands for environmental justice through proposals like the Green New Deal. Through extensive interviews with participants and her own experiences as an activist, the author provides a vivid portrait of communities struggling for survival against the corporate extraction of labor, mineral wealth, and the very breath of those it sends to dig their own graves.
