Blast vibration monitoring, instrumentation, and numerical modelling were employed for preliminary back-analysis of primary and secondary open stope hanging-wall behaviour within a highly stressed, foliated rock mass at No. 2 mine of Bousquet Complex of Barrick Gold Corporation. Blast vibration was monitored using triaxial geophones and a Blastronics BMX system. Hanging-wall behaviour was assessed on the basis of data obtained from grouted extensometers and a cavity monitoring system. FLAC numerical modelling back-analyses were carried out to examine hanging-wall stress and displacement distributions. A comparison of the final stope profile against projected near-field blast vibration and modelled stope conditions, provided an indication of the mechanisms influencing hanging wall stability.
