Abstract

Abstract: Taking backfill material for underground mine as the object of study， this paper aims to studying its rheological properties and strength characteristics by using the R/S+ rheometer and rock mechanics testing machine with the methods of experiment and theory analysis. And the visco-plastic fluid model of Papanastasiou was introduced to analyze the changing progress of viscosity and shear stress of tailings backfill. The results show that， the calculated results of this model were identical to the experimental results， thus it could be verified for theoretical calculation. In addition， the curve of shear stress-shearing rate at the different stress growth parameter was gotten， it is found that the viscosity and yields stress of backfilling develop with the increase of its mass concentration and the viscosity and yields stress of cementing tailings were higher than those of whole tailings at the same mass concentration. This study on rheological properties of tailings backfill are useful for designing filling station in mine.

Key words: mining with backfill, tailings fill, visco-plastic fluid, yield stress, rheological properties
