Abstract:This study aims to better understand the energy–frequency characteristics of microseismic wave propagation by monitoring particles in complex geology. Artificial seismic source experiments are conducted using a complex geological model, and variational mode decomposition method is applied to process the microseismic signals, obtain reconstructed microseismic signals and decomposition modes, and calculate the microseismic particle input energy and signal energy at each measurement point. Computations derived fr… Show more
“…Most rock burst processes are characterized by microseismic information precursors [109]. Most microseismic events and their energy evolution in the process of an instantaneous rock burst have self-similarity and fractal characteristics of time, energy, and space [110][111][112]. This indicates that the location and burst level of a direct rock burst can be predicted by microseismic monitoring information in most cases.…”
