中文摘要：
利用自行研制的含瓦斯煤三轴蠕变实验装置,对预制的成型煤样在不同围压和不同瓦斯压力下完成了蠕变实验。基于实验结果,研究了不同应力水平下轴向变形的变化趋势,分析了不同围压下含瓦斯煤的蠕变失稳特征。采用七元件非线性黏弹塑性河海蠕变模型对实验结果进行了分析,得到了含瓦斯煤的蠕变材料参数。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。
英文摘要：
By use of the triaxial creep loading device for gas-containing coal developed by the authors, a creep experiment is carded out. According to the experimental results, the variation of axial deformation under different stress states is studied, and the creep failure characteristics of gas-containing coal under different confining pressures are analyzed. The experimental results are analyzed by the seven-component nonlinear viscoelasto-plastic creep model （Hohai model）, and the creep materail parameters are attained. It is indicated that creep constitutive relation of gas-comtaining coal can be expressed by the nonlinear viscoelasto-plastic creep model correctly.
