VIBRATION PREDICTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vibration prediction method capable of predicting vibration at a prescribed point which may occur in accompany with future blasting.SOLUTION: A vibration prediction method includes: a measurement process for executing single blasting in a blasting execution region A1 and measuring basic single vibration waves at measurement points P1-P3 around the blasting executing region A1; a creation process for calculating magnitudes of a plurality of predicted single vibration waves at a prescribed point PZ occurring in accompany with the single blasting in an initiation hole 10, by using the magnitude of the basic single vibration wave measured in the measurement process, a powder charging amount into the initiation hole 10, and a distance from the initiation hole 10 to the prescribed point PZ, and creating a plurality of predicted single vibration waves on the basis of the plurality of calculated magnitudes and the waveform of the basic single vibration wave measured in the measurement process; and a calculation process for calculating the magnitude of a stepwise vibration wave by overlapping the plurality of predicted single vibration waves created in the creation process according to set initiation order and set time difference of seconds in initiation.SELECTED DRAWING: Figure 5
