Prototype Underground Demonstration Mine in Oil Shale Deposits.

PB297605

Publication Date	1979
Personal Author	Raymond, H. D.; Skelly, W. A.; Hoe, H. L.
Page Count	232
Abstract	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, Colo. 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. These include (1) chamber and pillar mining with backfill, (2) sublevel stoping with backfill, (3) sublevel stoping with full subsidence, and (4) block caving. The report also contains a detailed breakdown of projected capital and operating costs for the program.
