Ground Support in Mining and Underground Construction-Villaescusa & Potvin (eds.) © 2004 Taylor & Francis Group, London, ISBN 90 5809 640 8

ABSTRACT: This is a general overview on the use of paste backfill for ground support in underground mining 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 underground 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.
