Intelligent identification of the acoustic emission characteristics and crack propagation states during of coal failure based on the NRBO-XGBoost model

Intelligent identification of the acoustic emission characteristics and crack propagation states during of coal failure based on the NRBO-XGBoost model

ObjectiveThe dynamic hazards of coals are intimately associated with the complexity and uncertainty of coal failure, while accurately identifying the propagation states of coal cracks serves as a critical approach to investigating the instability failure of coals. However, the current identification...
