Book Description

Rock Fragmentation by Blasting contains the papers presented at the 10th International Symposium on Rock Fragmentation by Blasting (New Delhi, India, 26-29 November 2012), and represents the most advanced forum on blasting science and technology. The contributions cover all major recent advancements in blasting and fragmentation, from realistic treatment of the target rock; modelling, measurement and prediction of blast results; control of blast-induced damage, to special blast designs applicable to civil construction and demolition projects.

The latest developments on environmental issues associated with blasting operations such as vibrations, flyrock, and dust are also included. Rock Fragmentation by Blasting provides the state-of-the-art in explosives and blasting engineering, and will be a valuable source of information for researchers and practitioners involved in these areas.
