In mining industry, blasting operation is effective method to fragment rocks, supporting for the next operations in surface mines such as loading, and hauling works. However, blasting operation also impacts adversely on buildings and the surrounding environment, in which the vibration wave is one of the most severe impacts. Therefore, the implementation of the forecasting models of vibration speed contributes significantly to guarantee the safety of buildings located within the impact areas of the vibration wave. This paper employs the monitoring results of blasting activity at the Ninh Dan limestone quarry situated in Thanh Ba district, Phu Tho province, to develop different forecasting models that determine the effects of the ground vibration speed in the surrounding buildings. The results show that the models USBM and Ambraseys Hendron having more accuvate prediction than other models.
