Simulation of Goaf Gas Migration and Gas Controlling

摘要：

The gas problem of one coal mine in Shanxi province is numerical simulated with CFD on the basic of the theory for porous media flow.The simulation results show that the upper working face corners gas concentration will exceed the concentration limits in the area with gas content 5.2 mVt in the future producing of the coal mine.On the condition of the coal mine, the high gas tail entry is putted forward for the gas control and its location is determined by caculating.The gas contro-ling of the high gas tail entry is simulated by CFD.The simulation results show that the gas concentration is controlled in concentration limits by using high gas tail entry.
