Various parameters controlling three-phase foam seepage in a porous medium were simulated by computational fluid dynamics. The intent was to understand the three-phase foam seepage in the gob. The seepage velocities in the radiation zone, oxidative heating zone and asphyxia zone are 0-2.1 mm/s, 0-0.09 mm/s and 0-7.2 mm/s, respectively, when the inlet velocity is 5 m/s. A three-phase foam was proved to have accumulative and diffuse characteristics. 3D Max was used to simulate the seepage of three-phase foam in the gob, based on the results of the numerical simulations.
