摘要:The purpose of this study is to assess the influences of the gradation of tailings on the qualities of coarse tailings used for cemented paste backfill (CPB). Two reference mixtures of tailings (T and W) with CPB and four blended mixtures of tailings with CPB with T/W ratios (the weight ratio of tailings T and W) of 8/2, 6/4, 4/6, and 2/8 were prepared. The moisture content in hardened CPB generally increased as the tailings fineness increased. The relationship among tailings fineness, packing density and unconfined compressive strength (UCS) is discussed. As the tailings fineness increased, the flowability value decreased.
