Abstract

For the 884 working face of Zhuxianzhuang Mine, this study divides the spontaneous combustion three-zones in the goaf based on oxygen concentration. A model is established using Fluent software to simulate the impact of nitrogen injection at different locations and volumes on the three-zone distribution, aiming to determine the optimal nitrogen injection strategy. The study offers a more comprehensive optimization of nitrogen injection parameters compared to previous research, though the model has simplifications. Future exploration could incorporate more advanced algorithms and alternative inerting agents.
