Abstract

In this study, the effects of mass concentration, cement-bone ratio, and fine waste rate on the physical properties of cemented waste filling were analyzed. The results show that the bleeding rate decreases with the increase of mass concentration, and the effects of glue bone ratio and fine waste rate on the bleeding rate are non-linear. Increasing the mass concentration can enhance the compressive strength of the backfill but reduce the fluidity. The increase in fine waste rate leads to an increase in porosity, which affects the strength and fluidity of the filling body. The optimization of the gel-bone ratio is very important to balance the strength and fluidity of the backfill. The research results provide scientific guidance for mine filling technology, which is helpful to realize the safety, environmental protection, and high efficiency of mining.
