Study on the Gas Drainage Width Around Seam Roadway

More Information
  • Published Date: November 09, 2012
  • According to the gas seepape equation,coal seam gas flow equation,the state equation of ideal gas and the gas content equation,it established the coal seam gas seepage equations,and solved them with Fourier transformation.At the same time,the Comosol Multiphysics numerical simulation software was used to simulate the limit discharge width of the seam roadway.The results showed that the limit discharge width of roadway was increasing as the increase of the natural discharge time.
