ABSTRACT: Poor ground conditions in one area of the Golden Giant mine made the recovery of the stopes very difficult. In order to minimize ground rehabilitation and the dilution coming from the hanging wall a modified stope geometry was proposed. It was decided to extract these stopes as double width (28 m along strike rather than 15 m). The design was based on results from a detailed rock mechanics study which included the Modified Mathew's Stability Analysis, an instrumentation programme and a numerical model. This methodology has been effective in predicting potential ground conditions problems and has been proven as a valuable tool for the successful recovery of the first double width stope.
