构造煤,也称软煤,几乎在所有矿井均有分布,是瓦斯突出的必要条件。由于受断层、褶皱、层间滑动等地质构造作用,煤体结构遭受破坏,物理化学性质变化,瓦斯赋存特性改变,增加了煤体的复杂性和偶然性,也是瓦斯突出机理研究的难点所在。多年来,学者们对构造煤做了大量研究,取得了一 Structural coal, also known as soft coal, is distributed in almost all mines and is a necessary condition for gas outburst. Due to the geological structure of faults, folds and interlayer sliding, the structure of coal body is damaged, the physical and chemical properties are changed, the gas occurrence characteristics are changed, which increases the complexity and contingency of the coal body, which is also the difficulty in the study of gas outburst mechanism. Over the years, scholars have done a great deal of research on tectonic coal and have won the first prize
