Blasting vibration signals are often contaminated by trend terms and noise, stemming from environments, and instrument errors. This contamination hinders subsequent signal processing and analysis. To obtain a pure blasting vibration signal, a parameter-adaptive variational mode decomposition (VMD) m...
