| Abstract: | In Xinqiao Pyrite Mine, cemented backfill is costly and the fill body exhibits weak strength. In order to solve these problems, a research project was proposed in which fly-ash will used together with cement as a binding agent so as to reduce the consumption of cement . Systematic experimental study was carried out to determine the key technical parameters and a foundation has been laid out for enhancing cemented backfill and cutting filling cost. |

| Keywords: | Fly-ash Binding agent Filling cost |
