The drill and blast process is composed of many relatively simple steps. However, viewed in its entirety, blasting is highly complex. Multiple objectives (e.g. throw, fragmentation, flyrock, vibration) place constraints on designs that may not be mutually achievable. It is, therefore, not surprising that seemingly small changes in: geology, field procedures or product performance can lead to substandard results. The cost to the entire operation is high when blasting fails to meet minimum objectives making it imperative that root causes are quickly and accurately identified and corrected.

E&A has the experience to identify the source of blasting problems and bring performance back to a high level.
