How to Carry out Controlled Blasting of Rocks? [PDF]

The main objectives of controlled blasting techniques are to minimize the overbreak and fracturing of rock beyond the designated boundary of excavation to achieve smooth post-blast surface and to control wild flyrock and ground vibration within permissible limits. This objective is normally achieved by minimizing and making judicious use of explosives in the blast holes. []
