The purpose of this investigation was to identify innovative materials-handling systems suitable for spoil bank recontouring applications on abandoned coal mine lands. Nine specific sites, considered typical of abandoned mine lands in the United States, were examined. Recontouring costs for the sites were estimated first using conventional reclamation equipment (dozers, scrapers, etc.) as a base case, and second using large dragline stripping equipment for comparison. Using the cost and efficiency data generated during the studies, five innovative techniques were devised and applied to appropriate sites for cost estimation. The techniques involved an examination of the effects of modifying recontouring plans to reduce costs, the use of special bulldozer blade equipment, the use of special bucket pullback types of excavation systems, the application of hydraulicking, and the application of cast blasting to recontour highwall material.
