Book Description
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.

Book Description
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.

Book Description
This book presents the principles and practices of rock blasting for underground hard rock mining. It covers a theoretical background of the rock blasting technology and comprehensive case studies on different stages of rock blasting for underground metalliferous mining. It includes the discussions on burn-cut face blasting pattern, slot raise excavation methodology, and ring blasting methods. It further discusses different practical challenges associated with underground blasting, viz. ore dilution, ground vibration, wall instability, etc., and their possible solutions. The book also covers the recent advancements in methodologies to predict blasting outcomes and instrumentations for monitoring rock blasting operations. The book is a useful reference for rock blasting practitioners, mining engineers, professionals, and researchers. It is also a valuable reference for undergraduate and postgraduate students.
