The data developed in this study establishes the technical and economic feasibility as well as the improved health and safety characteristics of a novel mining concept. This concept is a modified longwall technique using prestressed tendons for roof control, longhole blasting for fragmentation, and remote mucking. The technical feasibility was found to be dependent upon the state- of-the-art, while economic feasibility was found to be dependent upon particular minerals and upon supply and demand. Since these two conditions are not necessarily coincident in time, the data are presented in the report in a manner that enables the mining engineer to perform a rapid preliminary technical and economic analysis for a specific property.
