Abstract
In this study, Rock deformation at the artificially advanced face was investigated by using the finite element code relating to the split blasting conducted in urban area. The maximum principal strain according to the detonation pattern and the detonation delay time at the rock surface was compared with the modeled blast section. As a result, it was found that the maximum principal strain was observed a difference depending on the detonation pattern at the rock surface, and the detonation delay time was an important parameter in split blasting.
