摘要
对铁法盆地的地质背景、煤系上覆地层和埋藏史、岩浆活动、煤体结构、煤阶分布、煤变质特征等进行了综合分析，认为铁法盆地的煤变质以浅成岩浆热变质作用为主；煤层热解气生成的时间、条件和方式受煤变质过程控制；
The geological background,overlying strata and buried history of coal measures,coal rank distribution and coal metamorphic characteristics in Tiefa Basin are analyzed comprehensively.It is considered that the coal metamorphism in tiefa Basin is dominated by the hypabyssal telemagmatic metamorphism;the timing,condition and way of the generation of coalbed pyrolysis gas are controlled by the coal metamorphism process;coal metamorphism and coalbed gas are both aspects of the same thing under the same geological environment.
