(PDF) Underground Mining with Backfill Tony Grice

Increased ore recovery results in longer mine lives.In some mining methods the backfill forms a working platform for people and equipment and therefore must be capable of supporting the traffic. Generally, cement is not required in this application.The placement of backfill underground directly reduces the quantity to be disposed on surface.
