ABSTRACT
Field scale measurements of blast-induced damage are not common either, and are limited to specific rock types and conditions. Ouchterlony et al. (1999 & 2001) and Olsson et al. (2002), for example, have contributed with the study of blastinduced damage in rock by conducting crack measurements in granite blocks and bench blasting. Other authors have used pressure sensors to estimate damage extent by measuring rock swelling (Brent & Smith 1996 & 2000) and gas penetration into cracks (Yamin 2005).
