AI Technical Summary
Existing mine ventilation systems lack dynamic adaptability and cannot update ventilation network parameters in real time. This leads to deviations in airflow path and air volume distribution analysis, a lack of accurate assessment and coordinated control of harmful gases, difficulty in responding quickly to gas anomalies, and insufficient targeting and effectiveness of control strategies, thus failing to effectively ensure mine ventilation safety and operational efficiency.
By constructing a real-time topology of the mine ventilation network and combining it with a multi-gas weighted risk assessment model, abnormal monitoring points are identified, pollution diffusion is simulated, a multi-fan collaborative control strategy is generated, dynamic risk areas are accurately delineated, and sets of isolation and exhaust fans are selected to achieve precise collaborative control of the fans.
It enables real-time adaptation to the mine ventilation system, improves the accuracy and reliability of abnormal monitoring point identification, enhances the foresight and control precision of risk management, optimizes the operating efficiency and stability of the ventilation system, and ensures the safety of underground operations.
