Study of dynamic models for coal gas dynamics (part 1)
Based on the extended formula of the Power law, partial differential equations for a compressible gas flow in homogeneous and heterogeneous coal seams have been set up. The measured parameters of coal gas dynamics were used to check the accuracy of the new nonlinear dynamic models for gas flow fields in coal seams. The results of the comparison revealed that the new nonlinear theory for coal gas dynamics is closer to the actual situation than the other two existing theories.
