Focus is on eliminating the hazards before they develop, on providing technology for inherently safer and more productive mining systems, and on providing adequate attention to the human element in order to assure safe and efficient interaction among mine workers, the environments they work in, and He equipment Key operate. The bureau's HSMT program consists of some I82 separate projects, with FYI994 funding of approximately $52 million.

The goal of the grouM control research element is to produce technology to maintain structurally sound and stable excavations or openings at mines and to reduce accidents caused by ground failure. The research emphasizes ground control methods and techniques and procedures to characterize rock masses, detection and monitoring systems, and ground hazard evaluations.

Minerals research emphasizes pollution prevention and control within the minerals cycle. Clean processing research focuses on mineral processing and extraction technologies and includes research on environmentally acceptable reagents or lixiviants for leaching of metals from ores, particularly for in situ leaching of copper sulfides and for developing cyanide-free leachants for gold ores.

Waste minimization arm recycling activities include research and technology development to minimize and recycle scrap, residues, and effluents from mineral processing operations. Efforts are also directed toward developing technologies for recycling specific advanced materials, such as new rare-earth magnets, alloys in rechargeable batteries, fiber-reinforced alloys, titanium aluminides, and other materials that are appearing in the marketplace.

The solid waste management and subsidence research element focuses on developing better technologies for the disposal of mining and mineral processing wastes from current operations and on ameliorating environmental damage caused by past activities. Although there are huge volumes of rock removed and disposed of during mining operations, the research targets those solid wastes containing toxic mews that can be rendered environmentally benign.

from responses to an annual solicitation. The bureau's current AML projects deal with subsidence issues, mine fires, water quality, revegetation, slope stability, and ground control around abandoned shafts and edits.

Those proposals that pass a final review then have detailed work plans, budgets, milestones, and authorizations prepared for initiation of the research once the final congressional appropriation is enacted.
