【Abstract】 On a microwave radiation triaxial loading experimental system with independent intellectual property rights, seepage experiments of coal samples were condected under the action of different microwave radiation power, radiation time, and effective force, the key factors affecting the permeability of coal samples were analysed, and the actual structural coal seam infiltration was reasonably predicted. According to the heating experiments, the fitted formula of surface temperature, radiant powers and radiation time of coal samples was obtained. The main influencing factors of permeability: effective force, radiated power, and their sensitivity were analyzed. The synergistic permeation of radiation power and radiation time in the form of energy consumption ratio was draum. It is concluded that higher microwave power infiltration should be selected.Through the analysis of the influence of radiation power, radiation time, and effective force on coal sample permeability, the mechanism of microwave radiation permeation increase is clearar, which has a theoretical reference and guidance for the capacity prediction of microwave radiant thermal recovery technology.更多还原
