Slimes draining from hydraulic sandfill operations often pose housekeeping problems, cause wear on mine dewatering pumps, and pose safety problems if dumped in ore passes. These problems are solved with paste backfill. The mining cycle time is less with paste backfill system because strength is achieved earlier than with hydraulic sandfill.
To a growing extent, thickened tailings are also used for underground mine backfill. This can increase productivity and reduce mine cycle times as well as surface TSF disposal …
