Technical and economic study of candidate underground mining systems for deep, thick oil shale deposits. Phase 1 report. [Piceance Creek Basin]

Technical Report ·
OSTI ID:7346418
; ; ; ; ;
Preliminary studies are reported on large-scale mining systems adaptable to the thicker oil shale deposits in the deeper central portion of the Piceance Creek Basin. The studies include an evaluation of the geology, hydrology, and resources of the Basin, evaluation of a potential prototype mine site, synthesis of rock mechanics data on Green River Formation oil shale, selection and preliminary design and cost evaluation of six potential mining systems and a ranking analysis to aid in selecting the most promising system. The relative merits of each mining method were defined and the followidng candidates were selected as most promising for detailed design and analysis under Phase II of the contract; (1) chamber and pillar mining with spent shale backfill; (2) sublevel stopping with spent shale backfill; (3) sublevel stopping with full subsidence; and (4) block caving mining using LHDs (load, haul, dump equipment). Health and safety and environmental aspects are also considered. (JGB)
