Gold and Diamond Mining
Overhand cut and fill mining involves excavating a horizontal slice of an orebody, then filling the void with a backfill material - typically mine waste or rejects from the processing plant . After backfilling, another slide is taken on top of the previous one, with the process proceeding until the orebody extraction is complete. Underhand cut and fill mining also starts with a single horizontal slice, but subsequent slices are removed from below the initial one. In underhand mining, the backfill material usually has cement added to make a low grade concrete roof that is sufficiently strong to safely work under.
