Coal mine coal dust explosion risk dynamic evaluation and explosion suppression system

By integrating multi-source information and active chemical detection, the risk of coal dust explosion in coal mines is dynamically assessed, enabling early warning and precise coordinated explosion suppression. This solves the problems of single risk assessment and poor linkage of explosion suppression devices in existing technologies, and enhances the proactive prevention and control capabilities for safe production in coal mines.

AI Technical Summary

Technical Problem

Existing coal mine safety monitoring systems have a single risk assessment dimension and lack integration with the dynamic distribution of personnel and changes in regional temperature fields. Traditional sensor early warnings are lagging, and explosion suppression devices are fixed in location and have poor linkage, making it difficult to achieve early and accurate early warning and coordinated explosion suppression.

Method used

The system employs a sensing module to acquire multi-source information, including dust concentration, methane concentration, temperature, air pressure, and personnel status parameters. Combined with an active chemical detection module, it analyzes the air in the ventilation ducts. The central processing module performs multi-level information fusion and time-series analysis to dynamically assess risks. Finally, the system coordinates with the mine system through a linkage control module to execute explosion suppression actions.

Benefits of technology

It enables early and comprehensive perception and dynamic assessment of coal dust explosion risks, improves the timeliness and accuracy of early warnings, enhances the system's response to risk evolution and explosion suppression effect, and forms a proactive prevention and control system.
