摘要

Abstract

Aiming at the key problems of poor fluidity and low strength of ultra-fine tailings cemented filling slurry

this study systematically explored the regulation law of a functional synergist ( FS ) on the performance of filling system with ultra-fine tailings in Fankou Lead-zinc Mine as the object. Through full factorial experiments

the coupling effects of FS content

slurry concentration

cement-sand ratio and other factors on the performance of the system were quantitatively analyzed

and the rheological and strength prediction models were constructed based on the response surface method. The study found that FS has an optimized dosage window of 0.3% -0.5%

which can maintain excellent fluidity at a high concentration of 78%. The mechanism of synergistic improvement of macro performance is that FS can effectively disperse flocculation structure and promote cement hydration by significantly changing the surface electrical properties of particles and slurry stability. This study provides a reliable quantitative design tool and theoretical basis for the ratio optimization and cost control of ultra-fine tailings filling.
