An overview on the use of paste backfill technology as a ground support method in cut-and-fill mines

This is a general overview on the use of paste backfill for ground support in underground min- ing operations and as such, concerns backfill design parameters (internal pressure development, required strength and mix optimisation), its pumping qualities (consistency and rheological) and delivery to an under- ground operation through pipelines. Emphasis was placed on the optimization of the paste backfill mix for backfill design, work safety and expense to the mining operation. This is because of the 20% representative costs related to backfilling, 15% represents the binder costs.
