Title: Area terrace pit coal mining systems: volume 1--technical and economic evaluation of terrace pit mining systems. Open file report (final) Sep 1977-Jul 1980

Technical Report ·
OSTI ID:5177408

This report is principally concerned with the engineering and economic feasibility of area surface coal mining systems other than draglines. This analysis evaluates shovel-trucks, shovel-crusher-conveyors, and shovel-rail excavation and haulage systems for an assortment of geologic environments and production rates in the Powder River Basin (PRB). Shovel-trucks, front-end loader-trucks, and shovel-crusher conveyors were studied in a multiseam, dipping geologic area of the Four Corners region. The Texas lignite engineering and economic research involved bucket-wheel excavators (BWE), BWE-backhoes, and scraper-backhoe combinations for overburden and coal excavation. The PRB truck-shovel study utilized the most recent computer simulation available in both the design and cost analysis. Detailed engineering analysis, followed by in-depth operating costs result in a complete evaluation of each mining system. Cost comparisons of the different mining systems under similar geologic and production constraints are presented to illustrate the estimated capital investment and production costs per ton of coal and bank cubic yard of overburden.
