探讨了构造煤动力变质作用的生烃问题，认为：①构造煤在动力变质过程中有烃气形成；②动力变质作用所形成的烃气对瓦斯含量、瓦斯压力的增加起着重要作用；③重烃是在构造煤动力变质过程中形成的．
The hydrocarbon generation problems of tectonic coal metamorphism are discussed. It is considered that: ①There is hydrocarbon gas formation in tectonized coal during dynamic metamorphism; ②The hydrocarbon gas formed by dynamic metamorphism plays an important role in the increase of gas content and gas pressure; ③ Heavy hydrocarbons are formed during tectonic coal metamorphism.
