Production dozing of cast material is a cost-effective method for improving dragline or mobile equipment overburden removal. Yet dozer productivity is reduced during the part of the process that requires the dozers to cut material away from the high wall. One solution is to use a hydraulic excavator to remove this material and throw it into a windrow for the dozers. By freeing up the dozers for more productive work, the overall system productivity increases 25 percent, and the cost per yard moved is reduced by up to 10 percent. Dozer fleet sizing can be determined to match a specific production schedule or can be sized to balance with an excavator's production.
