It is indicated that creep constitutive relation of gas-comtaining coal can be expressed by the nonlinear viscoelasto-plastic creep model correctly. 实验结果与该模型的理论值吻合较好，表明河海模型能正确描述含瓦斯煤的蠕变本构特性。
An effective stress calculation formula for coal containing gas is proposed coupling with the swelling stress of gas adsorption in the effective stress principle for porous media. 摘要首先在多孔介质的有效应力原理中引入瓦斯吸附的膨胀应力，推导出了适用于含瓦斯煤岩的有效应力计算公式。
