Strip-mining Techniques to Minimize Environmental Damage in the Upper Missouri River Basin States.
NTIS: PB 245 843 :53 pages
To meet escalating energy requirements, substantial increases in production from the strippable coal and lignite deposits in eastern Montana, western North Dakota, and northeastern Wyoming already have occurred, and further expansions are expected at least until the year 2000. Such production, attributable largely to rising demand for low-sulfur coal, must be accomplished with a minimum of adverse effects on the environment. Information on geology, climate, and current land use in the upper Missouri River Basin is presented in this Bureau of Mines review as a guideline to what operators may expect during and after mining. Proven methods of protecting the air and water from pollution and of restoring mined land for other uses are described, and untried methods of land reclamation, some with equipment yet to be manufactured, are discussed as possible means of maintaining esthetic values in the basin. Costs incurred to protect the environment are part of the production cost and thus are borne by the ultimate consumer. Unit production costs are less for the thick coal and lignite deposits of the basin than for the thinner but higher btu coal deposits of the eastern and midwestern United States. Precise comparisons of environmental protection costs between mines in such disparate areas cannot be made because of differences in physical conditions, accounting procedures, and other variables.
