Outstanding advances have been made in the technologies of using cemented fill through out the world. The choice of a cemented fill system, its mix composition and their proportion depend on the stope geometry, strength requirement, strata condition, working condition and the economy of the mining method as a whole. The strength of any cemented fill increases considerably with the increase in the cement content and decrease in the water to cement ratio. The ratio of cement to tailing by weight generally varies from 1:20 to 1:40 depending on the stope geometry and free standing height required. As far as substituting ordinary Portland cement with less costly bender alternative is concerned, fly ash can replace Portland cement in proportion of 30 percent where as if ground granulated blast furnace is used as a binding agent, Portland cement can be replaced by 50 percent. As far as activators (used to activate binding agent) are concerned, the use of cement is most favourable. Once a cemented fill system is selected, a proper fill plant is necessary to facilitate successful placement of the slurry mix into the voids. A typical layout of such a fill is described in this paper.
