Abstract
The objective of this paper is to review advances in the art of borehole (slurry) mining made by the Bureau of Mines. Historical and general background information on borehole mining is given. The borehole mining concept is defined and justified in terms of economics, health and safety, the environment, and resource conservation. This is followed by a description of the design of a prototype borehole mining tool (bmt) developed by the Bureau of Mines. Next, the application of the bmt in the extraction of metallurgical coal from steeply pitching seams near Wilkeson, Washington, during 1975-76 is described. Finally, the Bureau efforts in applying borehole mining to the extraction of uraniferous sandstone is described. Bmt design changes appropriate to uranium mining are described along with production, reliability, and reclamation data taken during 1977-78.
