This report contains a summary of designs, specifications, costs, and schedules developed for a prototype oil-shale demonstration mining program to be undertaken at the Horse Draw site in the Piceance Creek Basin, Rio Blanco County, Colorado. The objective of the program is to assess the feasibility of extracting oil shale and associated saline minerals from deep rich oil shale zones that occur within the central portion of the basin. Four mining systems were specified for demonstration including chamber and pillar mining with backfill, sublevel stoping with backfill, sublevel stoping with full subsidence, and block caving. Commercial-scale designs for each system were modified and scaled down as required to achieve program objectives.
