Predicting the peak particle velocity from rock blasting operations using Bayesian approach [PDF]
Acta Geophysica, 2022 AbstractMeasuring the blast-induced ground vibration at blasting sites is very important, to plan and avoid adverse effects of blasting in terms of the peak particle velocity (PPV). However, the measurement of PPV often requires time, cost, and logistic commitment, which may not be economical for small-scale mining operations.
