Advances in mechanics of cemented rock-tailings fill research

Cemented Rockfill(CRF) can deal with mining waste rock and without pollution, it had been accepted and applied, because its absorbed waste rock and cemented backfill technology predominance. This paper summarized the development of backfill technology, and expatiated mechanics principle of cemented backfill、cemented backfill material and influence factors of strength of cemented backfill. It discussed classical mechanics strength theory and international cemented rock-tailings fill research.
