Through the restoration of coal rank distribution pattern to the basin prototype,it is considered that the coal rank actuality was already basically accomplished under the hypozonal metamorphism before the present structural configuration appearing.
通过恢复原型盆地煤类分布规律,认为其变质现状是在深成变质作用下、现存构造面貌发生前已基本完成,勘查资料表明,贯穿井田中部的F2逆冲断层将原向斜构造切割成了两个倾向南西的单斜构造形态,逆冲断层将盆地深处的地(煤)层推覆到地表露头,使得浅部煤层变质程度高于其深部的煤层。
