Preliminary Economics of Mining a Thick Coal Seam by Dragline, Shovel-Truck, and Scraper Mining Systems.

PB277113

Publication Date	1977
Personal Author	Bertoldi, M. J.
Page Count	34
Abstract	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.
