New Mining Technologies Resulting from U.S. Bureau of Mines Research.
Proc 11th World Min Cong Belgrade Yugoslavia 1982 May; B:397-409
The Bureau of Mines conducts a wide variety of research to improve the technology associated with the exploitation of mineral deposits. These studies, which cover all aspects of surface and underground mining, have produced a number of innovative techniques and equipment that have significant potential benefits in minerals extraction. This paper examines a number of recent developments that have been the product of Bureau of Mines research, with emphasis on the problems to be overcome, the research approach, the resulting developments, and potential benefits. Specific items to be addressed include a retractable drill bit for exploration and development drilling; developments in borehole mining techniques for the exploitation of small, near-surface deposits; new low-headroom crusher developments for room-and-pillar mining; and large-scale crusher developments for open pit mines. These developments have application to a wide variety of minerals exploitation including uranium, limestone, copper, lead, and zinc, as well as problems in minerals exploration.
