BLAST IMPACT ASSESSMENTS
Some blasting projects require a Blast Impact Assessment (BIA). This assessment pertains to offsite blasting risks and impacts such as ground vibration and airblast levels, and determination of flyrock throw distance and clearance zones. BIAs typically contain predictive modelling of blast designs to determine if compliance with relevant blast vibration limits and other conditions can be achieved and identify areas in which blast design may need to be modified to maintain compliance. BIAs are usually required for long-term operations such as mines and quarries with nearby sensitive receptors.
Terrock has considerable experience producing both BMPs and BIAs. Please contact Terrock if you require assistance.
