This experimental study presents the rheological properties and strength characteristics of cemented unclassified tailings backfill (CUTB).
The particle size distribution and chemical properties of tailings from the Shizhuyuan lead-zinc mine were examined experimentally.
A series of rheological properties and uniaxial compressive strength (UCS) tests were conducted to study the relations between the rheological properties of CUTB and two factors of cement-tailings ratio (c/t) and solid content (SD).
The two-factor nonrepetitive analysis of variance (ANOVA) method was used to study the sensitivity of rheological properties to two factors of c/t and SD.
Relations between UCS performance of CUTB and c/t, SD, and curing time (CT) were discussed.
Results indicate that CUTB samples exhibit obvious shear thinning characteristics and the rheological process is the result of multiple rheological model composites.
Yield stress and viscosity of CUTB increase with the increase of SD and c/t as quadratic.
The solid content is the most important factor for the rheological properties of CUTB, followed by c/t.
UCS of CUTB increases exponentially with the increase of SD and increases with c/t as quadratic.
The larger the ratio of c/t, the greater the influence of the CT on the increasing strength of CUTB.
The smaller the c/t, the slower the increase of the CUTB’s strength with the increase of the SD.
The findings of this study can provide the efficient mix proportion of backfill slurry for the backfill mining design, so as to have better performance of the underground mining structure and reduce the cost of backfill mining.
