97.78%
XGBoost Prediction Accuracy
The study evaluated eight ML algorithms, with XGBoost achieving the highest accuracy of 97.78%, 98.25% recall, and 97.86% F1-score, demonstrating strong generalization in complex coal mining scenarios. This highlights XGBoost's exceptional capability in handling the heterogeneity and complex interactions inherent in multimodal physiological data for safety prediction.
| Model | Accuracy | Precision | Recall | F1-score |
|---|---|---|---|---|
| XGBoost | 97.78% | 97.61% | 98.25% | 97.86% |
| CatBoost | 94.89% | 95.71% | 96.04% | 94.56% |
| RandomForest | 95.56% | 97.24% | 96.49% | 96.64% |
| LightGBM | 93.33% | 93.82% | 92.67% | 92.53% |
| KNN | 75.56% | 72.60% | 74.00% | 72.41% |
While XGBoost led, other ensemble methods like CatBoost and Random Forest also showed strong performance, highlighting the robustness of gradient boosting approaches for multimodal data classification in safety-critical applications.
TP/ms²
Most Influential Feature
SHAP analysis identified the total power of the heart rate variability spectrum (TP/ms²) as the most important feature influencing behavior prediction across all states. This physiological indicator reflects the operator's load and neural responses, crucial for understanding behavioral states in dynamic industrial settings.
Understanding SHAP-Driven Feature Insights
SHAP analysis quantifies the contribution of each physiological feature to behavioral state predictions, providing crucial transparency to the model's decision-making process. Beyond TP/ms², other significant contributors include: median frequency of electromyography signals (EMF), the difference between maximum and minimum respiration values (Range), and the root mean square of electromyography signals (RMS). The analysis revealed that TP/ms² and EMF exhibit accelerated growth patterns in their predictive influence, whereas Range and RMS show distinct boundary effects, with their influence diminishing beyond certain thresholds. This granular understanding of feature impact is vital for developing targeted and effective safety interventions.
Deriving Actionable Safety Rules
Through decision tree segmentation applied to SHAP values, this study extracted critical thresholds for key physiological features, enabling the generation of actionable rules for safety improvement. For instance, specific value ranges for EMF and Range were found to be strongly correlated with higher probabilities of unsafe behaviors during preparation and execution phases. By monitoring if EMF values fall below 0.42 or if Range values exceed 10.99, real-time alerts can be triggered. These insights allow for the creation of precise, data-driven protocols that guide interventions based on objective physiological indicators, shifting from reactive to proactive safety management.
| Phase | Index | The range of values | SHAP mean |
|---|---|---|---|
| Preparation | Y | (YMin - 14.01) | 0.58 |
| Preparation | RMS | (RMSMin - 17.45) | 0.51 |
| Preparation | EMF | (EMFMin - 0.42) | 0.83 |
| Execution | TP/ms² | (25543.53, _TP/ms²Max) | 0.51 |
| Execution | Range | (RangeMin, 10.99) | 1.00 |
| Execution | SPF | (10.90, SPFMax) | 0.37 |
These thresholds, derived from SHAP values, provide concrete guidance for setting up intelligent monitoring systems to detect and mitigate unsafe behaviors in real-time.
Practical Validation in Simulated Mining Environment
Background: The study utilized a laboratory-simulated coal mining environment to replicate hazardous conditions, including equipment failure and high gas outburst risk. University student participants performed a circuit maintenance task while physiological and EEG signals were continuously captured.
Challenge: Traditional safety management often relies on manual inspections and retrospective analyses, lacking the capacity for continuous, real-time monitoring. This limitation is particularly critical in dynamic and high-pressure underground mining, where timely detection of unsafe behaviors is essential for accident prevention.
Solution: The developed framework integrates wearable sensors and AI/ML models to continuously monitor physiological signals, predict behavioral states (baseline, preparation, execution), and identify unsafe actions in real-time. SHAP analysis enhances the interpretability of these predictions.
Outcome: This approach provides a scientific basis for real-time safety monitoring, enabling proactive interventions and enhancing overall safety protocols in high-risk industrial settings. The predictive capability supports proactive hazard mitigation and intelligent safety management, moving beyond reactive accident responses.
Advancing Predictive Safety: Limitations and Future Work
While promising, the study's generalizability is currently limited by the use of university student participants instead of actual miners. Future research must involve validation with actual miners to capture context-specific patterns and enhance practical relevance. Further work should focus on expanding datasets, exploring causal relationships beyond mere correlations, and optimizing feature selection techniques. For real-world deployment, critical considerations include addressing hardware requirements (multi-core processors, 2–4 GB memory, BLE/Wi-Fi connectivity, and high-quality sensors for heart rate, EDA, PPG), ensuring device battery life, comfort, signal quality in the presence of environmental interference (dust, humidity), and robust data privacy protocols. Successfully addressing these will enable widespread adoption of real-time predictive safety management systems.
