Platform Overview
The system consists of a full-laser beam tube monitoring device for coal mine spontaneous combustion, a distributed optical fiber temperature measurement device, a data transmission network, and ground software with a B/S architecture.
A gas sampling pump cyclically samples monitoring points. Using laser spectroscopy analysis technology, it monitors the concentrations of ten signature gases related to coal spontaneous combustion in real time and with high accuracy, including O₂, CH₄ (methane), CO, N₂, CO₂, C₂H₄ (ethylene), C₂H₂ (acetylene), C₂H₆ (ethane), H₂S (hydrogen sulfide), and NH₃ (ammonia).
Temperature-measuring optical cables are laid along the line to obtain the real-time temperature of the entire mining area roadway. Multi-parameter sensors are deployed in the return air corner and goaf to build a full-range fire monitoring network system for the working face, enhancing fire prevention and control capabilities in key areas.
Data is transmitted to the ground server software in real time for fusion analysis. Based on the coal spontaneous combustion early warning index model, it realizes trend prediction, hierarchical early warning, and linkage disposal. Combined with the advancement of the working face, it dynamically analyzes and visualizes the spatial evolution law of the “oxidation zone, heat dissipation zone, and suffocation zone” in the goaf, providing a decision-making basis for mine fire prediction and prevention.
