Article Synopsis
- This paper develops a method to predict smoke backlayering length in tunnels affected by double-source fires through theoretical analysis and new formulas.
- It introduces fire power and distance influence coefficients to enhance the accuracy of predictions, originally based on single-source fire scenarios.
- The results show that the revised prediction formula closely matches simulation values, which can aid in understanding and managing smoke in tunnel fire emergencies.
Injecting nitrogen into goaf has been widely adopted for preventing fire hazards in coal mines. In this paper, the coupling relation between different locations of negative pressure of cross-cut drainage and nitrogen injection was investigated. The minefield data collection was carried out by an in situ beam tube system on the intake airway and return airway of the mine goaf.

The charge distribution, structural parameters, and molecular orbital were analyzed to determine the active sites existing in the structure of aldehyde group. Then, a chemical reaction model including five elementary reaction sequences was established.
