Mine fires mainly arise from spontaneous combustion of coal seams and are a global issue that has attracted increasing public attention.
Particularly in china, the closure of coal workfaces because of spontaneous combustion has contributed to substantial economic loss.
To reduce the occurrence of mine fires, the spontaneous coal combustion underground needs to be studied.
In this paper, a computational fluid dynamics (CFD) model was developed for coal spontaneous combustion under goaf gas drainage conditions.
The CFD model was used to simulate the distribution of oxygen in the goaf at the workface in a fully mechanized cave mine.
The goaf was treated as an anisotropic medium, and the effects of methane drainage and oxygen consumption on spontaneous combustion were considered.
The simulation results matched observational data from a field study, which indicates CFD simulation is suitable for research on the distribution of oxygen in coalmines.
The results also indicated that near the workface spontaneous combustion was more likely to take place in the upper part of the goaf than near the bottom, while further from workface the risk of spontaneous combustion was greater in the lower part of the goaf.
These results can be used to develop firefighting approaches for coalmines.
