Economic system analysis of coal preconversion technology: Phase I. Volume I. Introduction, summary, conclusions, and recommendations for research. Interim report for the period August 1973--July 1975

Abstract

Large-scale surface coal mining will play a key role in meeting the future energy needs of the United States. This project is directed at solving some of the problems of surface coal mining which would be encountered in supplying these energy needs. Fluor Utah, Inc., with Bonner and Moore Associates as subcontractor, was contracted by the Energy Research and Development Administration (ERDA) to determine and define the problems of designing large-scale (75,000 tons per day or greater) surface coal mines. This six-volume report presents the project findings of the 24 months of Phase I, which was concerned primarily with data gathering and development of mathematical models. Task summaries and conclusions and recommendations are presented in Volume 1; details of the study are presented in the remaining five volumes. During Phase I, a series of mathematical models was developed which can rapidly simulate new mining operations to aid in selecting equipment, designing a mine and a preparation plant, and determining capital and operating costs. Data files on coal deposits and mining equipment were compiled to support the models. This study has determined a need for improving availability of large excavating equipment; preparing a comprehensive coal preparation manual; identifying coal conversion plant requirements; training personnel required for future mines; promoting Federal efforts to encourage development of large-scale surface mines; financing the needed gasification and liquefaction industry; and developing and publishing additional data books and models.
