Abstract: Based on nine necessary basic assumptions of THM coupling model and theories of elastic mechanics,seepage mechanics and heat transfer,a real three-field and two-way coupled methatics model was established to reveal the connections amoung seepage,deformation and temperature difference within the system of coal containing methane.The model provided the definite conditions of equations about stress field,seepage field and temperature field,making progress in improvement of traditional seepage theory of coal seam methane and in theory of fluid-solid coupled model.
