Abstract: The production process of the fly ash-based compound cementation material and its application in total-tailing filling are described briefly.It is indicated that fly ash-based compound cementation material had an excellent performance and a low cost.It can entirely replace cement used as mine total tailing filling with a lower ash-sand ratio,better performance of flow and transport and lower filling costs.

Key words: Fly ash, Cementation material, Total-tailing sand, Filling cost
