Analysis of blast-induced ground vibration under surface

The blasting operation is vital in the construction of tunnels and channels or in mining when encountering hard geological environments to facilitate the progress of a project. The level and range of damage due to the blast are affected by the energy of shock waves generated after explosion. The control of seismic damage is a major issue in blasting engineering and cannot be neglected.

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. []
