Abstract

Summary

We develop, calibrate, and test a method to simulate the waveforms of mine blasts. Our model allows for spatial and temporal delays of the blast array, and accounts for the impact of charge weight on amplitude and bandwidth. We verify the method using a large station array deployed at an ore mine. Although the waveform fit at specific stations is often limited, we can demonstrate a detailed match of resonance modes and side-lobes in mean amplitude spectra. Our goal is to use the STF for deconvolution in seismic imaging and for PGV prediction.
