Study of the Dependence of Blast Induced Ground Vibration on Charge per Hole and Rock Strength
The objective of this study is to examine the influence of control and uncontrol blast parameters on the blast-induced ground vibration. The blast-induced ground vibration can be measured in the form of peak particle velocity and peak vector sum. In this paper, the effect of control blast parameter, such as charge per hole was considered, on the blast induced ground vibration was studied. This study showed the proportional relation with blast-induced ground vibration. It was observed that the PPV value was higher in the longitudinal direction as compared to the other two directions at the time of the variation in charge per hole. Further, the effect of rock strength on the blast-induced ground vibration was also examined which showed that the higher strength rock produces more ground vibration at the time of blasting.
