  • Tailingsfo Backfill of Tailings to Underground Workings

    For example a 'room and pillar' mining operation that uses backfill will be able to extract the insitu pillars containing ore. This is possible due to the cemented backfill acting as a support and preventing heading collapse and problems with subsidence. The backfill tailings are generally mixed on the surface with the cement in a small ...
