Equipping a Shaft and Mining Bulk Samples of Oil Shale, Nahcolite and Dawsonite.
NTIS: PB 83-114173 :81 pages
A 5-year program was planned for environmental research and geotechnical test work at the oil shale mining environmental research facility in the central Piceance Creek Basin, Rio Bianco County, Colorado. The facility consisted of a small-diameter lined shaft that would be equipped with a head frame, a hoist, and a surface plant to provide access to the deep, thick deposits of oil shale and the associated saline minerals including nahcolite and dawsonite. The objective of the research was to determine the potential effects of oil shale extraction upon the natural environment and the living and working environment, and to develop the technology required to resolve or mitigate the adverse effects. This report describes the equipping of the shaft and the mining of bulk samples of oil shale, nahcolite, and dawsonite from two levels.
