Comparative Costs Of Mineral Transportation Systems

Factors influencing Cost, systems available for transporting minerals, particularly on land, and methods used for comparing costs are reviewed. A case study presents comparative costs graphically for coal haulage, assumed in Queensland, by 31-6" gauge rail, belt conveyor, 120 ton road train, slurry pipeline, and transmission of electrical energy by transmission line. The effect on comparative results of alternative methods of including initial capital and capital replacement costs is considered and approximate break-even points between systems, bearing in mind the assumptions taken, are discussed.
