Cross-Scale Characterization of Rock Fracture Using Vibration Signal Features: Research Data

This dataset contains the original waveform records and processed numerical data supporting the study "Cross-scale characterization of rock fracture using vibration signal features". The dataset includes three types of vibration signals: laboratory acoustic emission (AE) signals from coal splitting experiments, mine microseismic (MS) signals, and seismic signals associated with the 2019 Changning Ms 6.0 earthquake in Sichuan, China. The data are organized into four categories: AE_Data, MS_Data, Seismic_Data, and Cross_Scale_Comparison. The dataset provides original waveform records, processed signal characteristics, frequency-domain analysis results, wavelet packet energy distributions, instantaneous energy data, multifractal analysis results, and cross-scale comparative parameters. These data support the time-domain, frequency-domain, and multifractal analyses presented in the associated manuscript.
