Assessment of effective factors in performance of an open stope using cavity monitoring system data: A case study

Stope wall failures result in ground stability problems, ore dilution, revenue loss, etc. This work assesses mined primary transverse open stope (32S 204) in AngloGold Ashanti-Obuasi Mine to address stability problems mine-wide. The stope (17 m strike length, 30 m wide, 27 m high and dipping 68°NW) has the Obuasi Fissure as its hanging wall boundary. Back analysis of the performance showed that major geological...
