Current and potential dragline reclamation usage was evaluated for U.S. coalfields based on data gathered and analyzed during field surveys, literature reviews, and contacts with manufacturers. It was concluded that current mining plans have been adapted to federal and state strip mine and reclamation laws in ways that limit the potential for dragline reclamation systems at active mine sites. At abandoned conventional contour mine sites in steep-sloping areas, such as central appalachia, it was found that dragline reclamation systems have great potential application and may be the only practical solution to many reclamation problems. Alternative dragline systems were examined for restoring abandoned sites, and it was concluded that a tower excavator system offered superior characteristics and should be evaluated and developed under field conditions.
