Preliminary economics of mining a thick coal seam by dragline, shovel-truck, and scraper mining systems.
Denver, CO: U.S. Department of the Interior, Bureau of Mines, IC 8761, 1977 Jan; :1-27
The purpose of this Bureau of Mines report is to describe the methods and establish the basic economics for dragline, shovel- truck, and scraper mining systems. An overall view of the techniques of preliminary design and the cost involved is presented. Considerations of equipment selection, emphasizing short-range evaluation of required equipment, and a long-range evaluation are considered at a constant production rate over the life of a hypothetical mine. Separate cost analyses for each system were based on 1977 equipment prices, prevailing wage rates, and associated mining costs. Specific engineering and cost breakdown for such items as access roads, transmission line installation, rail spurs, etc., are beyond the scope of this report.
