Blast Burden and Ground Vibration

How does you blasting burden influence your ground vibration? The burden of a blast is defined as the nearest relief to the borehole at the time that it fires. This can be either through a free face that the borehole was drilled near or a newly created face that was made from previous blastholes firing. […]

Scaled Distance for Blasting

Scaled Distance Calculations Scaled Distance is discussed and methods for calculation are given in this video for both ground vibration and air overpressure from blasting.   Scaled Distance is a commonly used technique for estimating the vibration and air overpressure from blasts. The term scaled distance is given because the blast where the weight fired […]
