Summary of Surface Blasting and Damages with Analysis of Two Mitigation Techniques – Presplit and Smooth Blasting

The main objective of smooth blasting is to leave a small berm of rock between the final face and the main blast, and then blast the berm with tightly spaced, lightly loaded blast holes. This forms a continuous crack between holes, giving an evenly contoured final face while keeping large blasts at great enough of a distance to limit damaging vibrations.
