Development of Optimal Terrace-Pit Coal-Mining Systems. Phase II Report. Volume 2. Terrace Pit Planning and Operations Manual (Farmington, NM; Terrace-Pit Vs Conventional Surface Mining; and Different Haulage Equipment)

摘要

This is a report on Phase II of a proposed five-phase project to be performed with US Department of Energy support, entitled The Development of Optimal Terrace-Pit Coal-Mining Systems. Phase I of the project dealt with design and economic analysis of terrace-pit mining concepts for surface mining of coal and comparison of these systems with conventional mining sceanrios. These comparisons were made for most of the major coal basins of the United States. Phase I included the publication of DOE Report No. ET/10023-3. Phase II consisted of a site-specific detailed mine design of conventional and terrace-pit scenarios, an environmental assessment, a terrace-pit planning and operations manual, and a data-collection plan. A total of four mining plans were developed for the selected site, the San Juan Coal Property near Farmington, New Mexico. Engineering data are developed in detail for four mining scenarios referred to as Terrace-Pit Mining, Conventional Surface Mining, Surface Mining with Belt Conveyors, and Concept for Mining by Property Owner. Each is described in this report and examined for technological and economic feasibility. (ERA citation 08:033073)
