Abstract Blasting vibration is a major adverse effect in rock blasting excavation, and accurately predicting its peak particle velocity (PPV) vital for ensuring engineering safety risk management. This study proposes an innovative IHO-VMD-CatBoost model that integrates variational mode decomposition (VMD) the CatBoost algorithm, with hyperparameters globally optimized using improved hippocampus optimization algorithm (IHO). Compared to existing models, proposed method improves feature extraction from signals significantly enhances prediction accuracy, especially complex geological conditions. Using measured data open-pit mine blasting, extracts key features such as maximum section charge, total horizontal distance, achieving superior performance compared 13 traditional models. It reports root mean square error of 0.28 cm/s, absolute 0.17 index agreement 0.993, variance accounted value 97.28%, demonstrating high degree fit observed data, overall robustness PPV prediction.

Debris flow, a typical non-Newtonian fluid, exhibits rheological behavior significantly influenced by particle size distribution. Traditional models often struggle with applicability and predictive accuracy in complex systems. This study proposes modified Herschel–Bulkley–Papanastasiou (HBP) model, incorporating distribution parameters to dynamically adjust yield stress shear viscosity, enhancing its describing debris flow under varying gradations. The model distinguishes the roles of fine coarse particles: particles reduce resistance through lubrication effects, while enhance viscosity via interlocking effects. To validate series experiments were conducted on 14 gradation conditions. Results showed HBP achieved fitting coefficients between 0.933 0.990, outperforming traditional demonstrating superior adaptability across different distributions. was further integrated into OpenFOAM framework for three-dimensional simulations flume experiment.

Force chain networks among particles play a crucial role in understanding and modeling dense granular flows, with widespread applications ranging from civil engineering structures to assessing geophysical hazards. However, experimental measurement of microscale interparticle contact forces flows is often impractical, especially for highly complex flow systems. On the other hand, discrete-based simulation approaches suffer extremely high computational costs. Thus, this study proposes an innovative machine-learning framework aimed at accurately predicting force using particle-scale bulk-scale features, novel topological parameters. A deep neural network was developed, achieving excellent accuracy 94.7%, recall 100%, precision 90.3%, f1-score 95% non-Bagnold type flow, where chains significantly affect characteristics. In addition, enrich future application proposed model, we introduce experimentally accessible feature set, demonstrating effective performance detecting chains. More importantly, our analysis importance Shapley additive explanations values facilitates informed decision-making when identifying real-world experiments. The architecture will be interest essential any proves exceedingly challenging.
