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 volume is devoted to the history and use by the United States of one of the Navy's least spectacular and most effective weapons. The effectiveness of the submarine mine has not decreased with the coming of the space age. So long as cargo ships cross the sea, this unspectacular weapon will remain a major factor in control of the approaches to harbors, and the shallow straits between seas. Robert Duncan has devoted most of his adult life to the generation and augmentation of competence in the application of growing science to the design, production, and use of mines for the U.S. Navy. He joined the staff of the Naval Ordnance Laboratory before it was known by that name, but in time to capitalize on the experience of the Navy with mines in World War I. He provided the technical leadership which was an important factor in keeping the art and science of mining alive in the Navy in the days of the depression. By so doing, he provided a basis for a hundredfold expansion of the Navy's effort previous to and during World War II. The hundreds of technical people who had the privilege of joining in this effort under Dr. Duncan's leadership will be happy to see this accurate and factual record of achievement. The experience recorded between these covers will serve as a guide to those still engaged in the development of this type of weapon, and the achievements made during World War II will be an inspiration to any who might be responsible for again expanding our national effort in mining, should the occasion arise.

Twenty years of work went into the writing of this: the first book to cover the history of mines and mining in North and South America. The text is enlivened by sketches of many miners the author got to know over the decades.

"Over the past five hundred years, North Americans have increasingly turned to mining to produce many of their basic social and cultural objects. From cell phones to cars and roadways, metal pots to wall tile and even talcum powder, minerals products have become central to modern North American life. As this process has unfolded, mining has also indelibly shaped the natural world and North Americans' relationship with it. Mountains have been honeycombed, rivers poisoned, and forests leveled. The effects of these environmental transformations have fallen unevenly across North American societies. Mining North America examines these developments. Drawing on the work of scholars from Mexico, the United States, and Canada, this book explores how mining has shaped North America over the last half millennium. It covers an array of minerals and geographies while seeking to draw mining into the core debates that animate North American environmental history generally. Taken together, the authors' contributions make a powerful case for the centrality of mining in forging North American environments and societies"--Provided by publisher.

The guidance provided focuses on individual skills of emplacing and removing mines, team and squad tasks, platoon and company organization and panning, and battalion/task force organization and coordination for successful obstacle reduction and breaching operations.
