Economic Engineering Analysis of U.S. Surface Coal Mines and Effective Land Reclamation.

摘要

This report covers technology of surface coal mining in the United States,including current problems,possible solutions,and projected future developments. It presents a coordinated, systematized,technical,economic analysis of the industry,describing practices and trends and giving cost data. To evaluate the mining techniques employed,the United States was divided into four regions where similar geologic and topographic conditions warrant similar mining practices. Mining methods for each region were examined in detail from a unit operation viewpoint. Economics of alternative mining equipment choices are discussed. The report covers surface coal mining from exploration through transportation to markets.
