Tracks: Session 2 - Field Blasting 1, Session 2 - Vibration 1, Session 2 - Vibration I

Speaker(s): Gustavo Azpilcueta

This is a blasting operation in a very remote place on the Aleutian Islands in the far west of Alaska. The short distance between the blast side and the camp facilities (50') represented a big challenge to avoid high vibration readings and fly rock issues. Electronic detonators were crucial.
