This book, the result of a congressionally mandated study, examines the adequacy of the regulatory framework for mining of hardrock mineralsâ€"such as gold, silver, copper, and uraniumâ€"on over 350 million acres of federal lands in the western United States. These lands are managed by two agenciesâ€"the Bureau of Land Management in the Department of the Interior, and the Forest Service in the Department of Agriculture. The committee concludes that the complex network of state and federal laws that regulate hardrock mining on federal lands is generally effective in providing environmental protection, but improvements are needed in the way the laws are implemented and some regulatory gaps need to be addressed. The book makes specific recommendations for improvement, including: The development of an enhanced information management system and a more efficient process to review new mining proposals and issue permits. Changes to regulations that would require all mining operations, other than "casual use" activities that negligibly disturb the environment, to provide financial assurances for eventual site cleanup. Changes to regulations that would require all mining and milling operations (other than casual use) to submit operating plans in advance.

This book focuses on the reclamation of waste storage areas, which constitute the main source of pollution during and after mine operations, especially issues with acid mine drainage and neutral contaminated drainage. It prioritizes the chemical stability of mine wastes over their physical stability.

The safe and economical construction of tunnels, mines, and other subterranean works depends on the correct choice of support systems to ensure that the excavations are stable. These support systems should be matched to the characterstics of the rock mass and the excavation techniques adopted. Establishing the support requirements, designing support systems and installing these correctly are essential elements in safe underground construction. This is a comprehensive and practical work which also gives access to user-friendly computer programmes which enable the investigation and design of support techniques. Details on how to obtain this software are also included in the book.

This book illustrates the advantages of the application of ground mechanic concepts to hard rock mining. It examines the ground stability for various mine layouts using specific case histories. The book deals with ground support, reinforcement, and stabilization of mining structures.

Underground Mining Methods presents the latest principles and techniques in use today. Reflecting the international and diverse nature of the industry, a series of mining case studies is presented covering the commodity range from iron ore to diamonds extracted by operations located in all corners of the world. Industry experts have contributed 77 chapters. This book is certain to become a standard for every practicing mining engineer and student alike. Sections include: General Mine Design Considerations, Room-and-Pillar Mining of Hard Rock/Soft Rock, Longwall Mining of Hard Rock, Shrinkage Stoping, Sublevel Stoping, Cut-and-Fill Mining, Sublevel Caving, Panel Caving, Foundations for Design, and Underground Mining Looks to the Future.

"The most comprehensive and interpretive study of the mining industry available to historians. . . . It is a book that will stand the test of time." -W. Turrentine Jackson, Technology and Culture "Mark Wyman's sympathetic account of the Western metal miners includes graphic details of their bitter struggle for unpaid wages, for industrial safety legislation, for corporate liability in the event of mine accidents and for workmen's compensation. . . . Throughout the book one finds the compassion and understanding that mark works in the best tradition of historical scholarship." -Milton Cantor, The Nation "Wyman has looked at miners in the larger context of American industrialization during the late 19th and early 20th centuries. In doing so, he has produced a stimulating, informative account of how this group of workingmen responded to changes in the work place brought on by changes in technology, corporate capitalism, and the shifting labor forces of the day." -James E. Fell, Jr., Pacific Northwest Quarterly "Wyman's compassionate and thoughtful study is an important contribution to the social history of western mining. Hard Rock Epic is also a significant addition to the literature on the process of industrialization. It amply demonstrates that no group in the American West was so deeply affected by the Industrial Revolution as the hard rock miners." -Jeffrey K. Stine, The Midwest Review "Hard Rock Epic is both a descriptive and analytical study of the impact of technology on the life of metalliferous miners of the West. It is thoroughly researched, drawing heavily upon primary sources and the most relevant recent scholarship concerning the hardrock men. The study is judicious and balanced. . . . [and] fits well into the growing body of scholarship on Western metal mining. Historians of labor and the American West will find this volume instructive and definite contribution to their fields of study." -George C. Suggs, Jr., The American Historical Review
