摘　　要：两淮煤田石炭二叠纪煤层的形成环境可划分为泥炭坪和泥炭沼泽两种类型,根据下伏沉积物的沉积环境又将其划分为若干亚型。不同环境煤层的煤体煤质、顶底板和夹矸均不相同水介质条件亦不同,泥炭沼泽是本区最重要的成煤环境。同一煤层在垂向上和平面上都可形成于不同的环境,不同环境间可以相互转化。The forming environmentsof the pormo-carboniferous seams in North andSouth Huaihe may be divided into two types:peat platform and peat swamp.In the lig ht ofthe depositional environments of the under-cying sediments,they may be classified intosome subtypes.In different forming environ-ments of a seams,coal mass,quality,roof,floor,water medium and pertings are different.Vartically and horizontálly,á sáme seámcould be(?)ormed in different environments,anddifferent environments could be converted eachother.
