Abstract
- The 2 858 tonne/d Meikle gold mine uses longhole open stoping for the main orebody with additional zones designed for extraction by cut and fill. It is the first shaft-accessed operation on the Carlin Trend. Both methods require cemented fill, and waste rock from the nearby Betze-Post open pit is used. Two fill mixes are produced: a high-strength (5.5 MPa unconfined compressive strength) mix for stopes to be undercut, and a low-strength (2.8 MPa) for stopes with rib exposure only. The backfill production and delivery system is described in detail.<br />The 2 858 tonne/d Meikle gold mine uses longhole open stoping for the main orebody with additional zones designed for extraction by cut and fill.
