Telfer gold mine consists of both open pit and underground operations, including a mature sublevel cave. Changes to mine design, the addition of subsequent sublevels, level footprint and increasing depth have all resulted in a changing seismic hazard, which is managed using a combination of seismic exclusions zones and dynamic ground support. The seismic hazard associated with high-stress slot development and production is well understood, but the progression of seismic activity into areas of low expected seismic hazard required a systematic upgrade to support.
A common theme is that changes to mine design have resulted in additional and changing seismic hazards, with areas of existing infrastructure no longer adequately designed or supported for the future expected demand. Understanding how changes to mine planning, addition of sublevels, footprint size and depth all effect the evolving seismic hazard, have been key to managing the hazard.
