摘要
在建立THM耦合模型所需的9条基本假设基础上,综合应用弹性力学、渗流力学、传热学理论,以含瓦斯煤系统为研究对象,建立了体现含瓦斯煤"三场"真正意义上的双向完全耦合数学模型。该模型包括含瓦斯煤应力场、渗流场、温度场方程和各场的定解条件,揭示了含瓦斯煤系统内渗流、变形和变温之间的内在联系。所建的模型是煤层瓦斯传统渗流理论和流固耦合理论的推进。
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.
