Preliminary Engineering and Economic Evaluation of Underspoil Haulage in Area Strip Coal Mines. Part I.
NTIS: PB 254 575 Available for Reference At Bureau Libraries :111 pages
With expectations of increased activity in surface coal mining, the federal Bureau of Mines has authorized a study to determine the preliminary economic and technologic feasibility of underspoil haulage in area strip coal mines and to identify geologic and geographic areas where such a system could be used. Underspoil haulage is the transportation of coal from the pit bottom by belt conveyor through a tunnel under the spoil. The objectives were met by literature search, data-gathering visits to several active area strip mines, and by analyzing various haulage systems that were superimposed on three model mines. Potential advantages of underspoil haulage include: (1) improved mine design, (2) lower mine operating costs, (3) improved land reclamation, (4) lower manpower requirements, (5) lower mobile equipment requirements, and (6) smaller, less sophisticated maintenance facilities.
