Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures
Deep Underground Science and Engineering, EarlyView.This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Hybrid Approach of Real-time Ground Motion Prediction for Earthquake Early Warning
SeismicaWe propose a hybrid approach for ground motion field prediction in earthquake early warning (EEW) systems, combining the Propagation of Local Undamped Motion (PLUM) method with advanced machine learning (ML) algorithms. Our methodology integrates PLUM's

An optimizing microseismic method for rock burst early warning based on mining production process
Deep Underground Science and Engineering, EarlyView.A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.
