Alternate methods of handling the parting between two coal seams. Contract research report, 1976
This report documents the results of a technical/economic feasibility analysis of alternate parting stowing techniques applicable to a representative, thick, multiseam surface mine in the Fort Union Coal Area. Methods are examined for their potential implementation, and an estimated operating cost per yard of material moved is developed. The methods are of two categories, castback or haulback. Haulback methods use truck haulage except with scrapers, and castback methods use direct stowage with no intermediate haulage equipment. Possible equipment combinations include draglines, shovels, hydraulic backhoes, bucket wheel excavators, scrapers, and front end loaders. This report evaluates the effective competitiveness of the various alternatives. (GRA)
