註釋A new approach to reclaiming the spoil areas produced by area-type mining operations has been developed. This system uses a machine known as a winch-dozer consisting of a pair of large back-to-back, scraper-type blades which are drawn by a wire rope across spoil piles, moving back and forth between a tailblock anchor and a drawworks winch unit developed as an attachment to a large crawler tractor. The program described in this report has produced a feasibility prototype system that was evaluated in operating mines. Based on operating performance and economic assessments of the feasibility prototype, the required characteristics of a production winch-dozer system were defined. The production system is a more cost-effective and energy efficient reclamation system compared to conventional techniques. Volume I of this report describes only those areas of the contract dealing with the design, development and testing of the winch-dozer system. Volume II of the report describes only those areas of the contract dealing with the development of a spoil-plane for leveling surface mine spoils.
