Slurry Transportation in Mineral Development in Japan

Abstract

Since slurry transportation systems are very useful to transport bulk materials, the systems are used in transporting ores and tailings in mining industries and in dredging harbors. This paper describes the characteristics of the slurry transportation systems, and the plan and application of the systems, written as follows, in mineral development in Japan. 1) The plan of Ishikari coal slurry tranport pipeline. 2) The hydraulic transportation system in Sunagawa coal mine. 3) The backfill slurry transportation system in cut-and-fill stoping. 4) The Oodate-Noshiro tailling slurry transport pipeline. 5) The pilot plant system of slurry transportation for sediment sand in Sakuma dam reservoir. 6) The manganese nodule mining system using airlift pump by National Research Institute for Pollution and Resources. 7) The control of gas kick and drilling mud flow in drilling well for methane hydrate production.
