Economic system analysis of coal preconversion technology: phase I. Volume III. Surface coal mining methods and equipment. Interim report for the period August 1973--July 1975
This report presents background information on present mining methods, operations, equipment and economics, in addition to problems and future trends. This information is required to support the development of the computerized modeling system which can be used to design large-scale surface coal mines. The modeling system is designed to handle the following five basic mining methods: (1) area stripping with draglines; (2) area stripping with shovels or loaders and trucks; (3) contour mining with draglines; (4) mountain top removal; and (5) dipping-seam open-pit mining. Each of these methods usually involves the following six operations: (a) topsoil removal, (b) overburden drilling and blasting, (c) overburden removal, (d) coal drilling and blasting, (e) coal loading and hauling, and (f) land reclamation. Data on track-type tractors, loading shovels, motor graders, rotary drills, scrapers, track-type loaders, trucks, walking draglines, wheel loaders, and wheel-type tractors were compiled and incorporated into computer data files for direct use of the modeling system. Mining costs are composed of capital, startup, and operating costs. Based on discounted cash flows for different return on investment rates, the FOB selling price of coal for given coal deposits will be determined in Phase II. (auth)
