Technical Report

OSTI ID:6872061
This Bureau of Mines publication compares the relative economics of three common coal strip-mining techniques. A general overview is presented relating to cost estimation for conventional dragline, shovel-truck, and scraper mining systems. A short-range equipment selection and long-term evaluation of mining a thick coal seam by each method also are considered. Cost analyses are based on 1977 equipment prices, wage rates, and associated mining costs. Specific cost breakdowns are considered only at a preliminary level and the operating cost estimate is based on published data on equipment performance and specifications.
