Study on Near-Field Spectral Characteristics and Vibration Control of Multi-Hole Blasting Based on VMD

To explore the spectral characteristics of near-field vibration signals from multi-hole millisecond-delay blasting in open-pit mines and the modulation effect of delay time on blasting energy distribution, field blasting vibration tests with multi-gradient delays were conducted taking an open-pit co...
