Description of Terrain to be Used in Evaluating the Lofted Mine Concept.

摘要

This report contains road and roadside terrain data pertinent to the evaluation of the Lofted Mine Concept for a portion of West Germany. Appendix A presents the profile data sheets representing 104 sites, 29 of which are accompanied by one or two sheets of on-site photographs. The information on the profile data sheets has been inferred from available topographic and soil maps and air photos. The data are presented on profile diagrams representing transects intercepting the road at right angles and extending 200 m to the right and left from the road center line. The data include a topographic profile along the transect line, slope orientation of the profile, and vegetation, soil, and roadwayy characteristics to the extent that the relevant data were inferable from the available data sources or from on-site inspection. Selection of the terrain characteristics for description was based on their presumed interactions with various functional phases of the proposed lofted mined system. The data constitute information exhibiting the considerable variation found within the study area. Analysis of the data in terms of performance of the proposed mine systems can be made by inference or more adequately by use of quantitative performance prediction models.
