摘　　要：在前人实验及理论分析的基础上，对瓦斯在煤体中的赋存形态、含瓦斯煤的特殊力学现象及瓦斯对煤体的蚀损过程进行了解释和半定量分析，得出的结论与实验规律相吻合。On the basis of experiments and theoretical analyses performed, the pore gas situation in coal, the mechanical characteristics and 'corrosion-damage' process of coal containing gas are studied and their mathematical models are put forward. These models can describe the experimental phenomena fairly.
