Abstract

Coalfield fire areas are widespread in the world, seriously threating the local ecological environment and the economic development. The complexity of occurrence and evolution challenges the scientific prevention and control of coalfield fire. Taking the Tanyaoqu coalfield fire area in China as the object, a physical model was established, and variations of temperature field during coal seam combustion were investigated. Moreover, the distribution of flow field in the fracture channel was examined by numerical simulation. The results indicated that the temperature field in coal seam expands faster in the dip direction than in strike direction, and this is related to the development pattern of fracture channel. The relationship between temperature and time was conformed to the logistic model, while the temperature decreased exponentially with extension of horizontal distance. The temperature variation in rock strata was similar, but lags behind those in the coal seam. Furthermore, at the initiative stage of coalfield fire, both the inflow and outflow happened in the initial fracture. It turned to be the air intake channel when new fractures formed. When the combustion center moved forward, the ventilation quantity decreased until the new fractures formed. Meanwhile, the ventilation quantity increased rapidly when the U-shape channel formed from the interval fractures. The variation of flow field in fracture channel provides a view that the air supply in coalfield fire area changes periodically with the closure and generation of fracture channels, which will influence the evolution of coalfield fire. These are of great significance for revealing the evolution process of coalfield fire.
