"Chattanooga Shale, underlying some 40,000 square miles in the southeastern United States, is considered to be a potentially large, low-grade source of uranium. The area in and near Dekalb County, Tennessee, appears to be the most likely site for commercial development. This paper deals with the mine design, mining procedures, equipment requirements, and operating maintenance cost for an underground mining complex capable of producing 100,000 tons of Chattanooga Shale per day for delivery to a beneficiation process."
