Flow properties of paste made of dewatered mine tailings and a binder were investigated by means of a transportation test using pipelines of 4 inches and 8 inches in diameter at Toyoha Mine. In addition to full-scale tests at the mine, laboratory tests using small-scale pipes were carried out. In this paper, results of flow properties of the paste are presented and various problems during underground backfill are described.
