The contractor investigated and evaluated all potentially feasible methods for large-scale mining of the thick oil shale deposits in the deeper central part of the Piceance Creek Basin of northwestern Colorado. Technical and economic data were obtained, preliminary layouts and designs were prepared, and pertinent operating features and cost data were analyzed and evaluated. The relative merits of each mining method were defined and the following 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 stoping wiht spent shale backfill. (3) Sub-level stoping with full subsidence. (4) Block caving mining using load-haul-dumps.
