Research on flow shift law of porous media in goaf base on the unsteady airflow theory
Base on the unsteady flow theory, supported by the theory of mine ventilation, the theory offluid mechanics, the theory of infiltration ow through porous media, mathematical model of porousmedia about air flow uctuating in goaf of mine is establishedfeatures of distribution of flow fieldin goaf when air flow uctuating are researched by numerical simulation, distribution of ow field istested with the help of the flow field testing experiment model which is designed and done by oneselfown. The results show: the results of numerical simulation and experiment are quite corresponding,mathematical model of ow field of porous media in goaf of mine established in the paper can be usedto research distribution of ow field in goaf and flow shift law.
