Blasting at very close proximity to urban areas is typically a situation where both local communities and mining stakeholders get nervous.The context becomes logically even more tensed when the blasting operations have to be performed above an old under- ground mine.When mitigating subsidence risks requires firing the largest possible shots, the nuisance control (flyrock, vibration, and noise) required by local and national regula- tions, contrarily urge for being more conservative.
