Abstract: On the basis of analysis of tailings cementing fill cost, the ways to reduce the fill cost in Kangjiawan Mine were discussed such as the addition of slag, the adoption of cementing rockfill and the prolongation of continuous filling time. If the measurements suggested are adopted, the fill cost can be greatly reduced and better economic benefit can be achieved.
Key words: fill cost cement consumption continuous filling time cementing rockfill
