To reveal the evolution law of coal skeleton deformation during the process of
CO2 flooding and displacing CH4 in coal seam, a fluid-solid coupling
mathematical model of CO2 injection enhanced CH4 drainage was established based
on Fick’s law, Darcy’s law, ideal gas state equation, and Langmuir equation.
Meanwhile, numerical simulations were carried out by implementing the
mathematical model in the... hiện toàn bộ
