This paper introduces a practical methodology for analyzing vi┬Čbration records in view of improv┬Čing blast designs and preempting anomalous vibrations. This technique, which is based on empirical data, uses a blasting-efficiency determinator (BED) as an indicator of vibration-energy transmission. The method was tested using data from a blasting event at an open-cast coal mine in the province of New Brunswick, Canada. The results derived from the BED values showed that geology and delay timing were probably the principal factors that induced high-intensity vibration propagation.
