A preliminary systems analysis of coarse-particle coal slurry pipelines as a haulage method was performed. Two literature surveys on state-of-the-art longwall mining and slurry transport technologies were prepared. Two representative longwall systems were designed, one with conventional haulage and one with slurry haulage. The two systems were then compared on the basis of cost, safety, and reliability. It was concluded that for the case of a two-face longwall mine, a coarse slurry transport system does not have a clear-cut cost advantage over a conventional system. However, indications were that a cost advantage could occur under different analytical conditions such as (1) a larger scale mine, (2) if intangible benefits were quantified, and (3) if new generation technology rather than currently available technology were applied.
