Reconnaissance and processing of impounded coal wastes. Annual report, October 1, 1979-September 30, 1980

Technical Report ·
OSTI ID:7049932
This investigation funded by the Department of Energy, involves sampling, testing and analyzing coal impoundments in Alabama to determine the quantity of coal in place, and the quantity and quality of recoverable coal in each impoundment. A second objective of the work is to sample the washery wastes currently discharging into the impoundments, and to determine the quantity and quality of coal recoverable. During the first three quarters of FY 1980, exploration of four waste fine coal impoundment locations have been completed. The four impoundment reserves proven to date contain 1,951,000 tons of raw coal of which 761,000 tons of clean, marketable coal can be recovered. The raw coal tons, clean coal tons, percent recovery and percent ash are shown in a table. During the fourth quarter of FY 1980, exploration of three additional waste fine coal impoundment locations were completed. A total of over 4700 feet in 150 holes were drilled. Exploratory drilling and sample analyses have indicated proven reserves of 519,575 tons of raw coal from which 190,801 tons of clean coal can be recovered. Sink-float data from the impoundments indicate that a recovered clean coal product assaying 6.9 percent ash, 0.85 percent total sulfur with a heating value of 13,357 Btu per pound can be produced. Summary data of this reserve are shown in tables.
