Abstract

Blasting induced seismic signals are assumed to behave linearly. This assumption, provides easiness both in adjusting "delay times" to minimize ground vibration and in fragmentation process of blasting. Being the signature of a group blast, signal from pilot blast should be calibrated. This calibration requires a knowledge of the effects of controllable parameters of blasts on seismic signals. In this study, the effects of explosive amount, depth of the hole, surface and inside-hole delays and bench-blasts on the seismic signals were examined.
