Principles of the method are that all ash composition comes from the minerals and clasts incoal seams, so it is possible to reversely infer the sorts, contents and grading law of the minerals and clasts of coalseam from the sorts, contents and grading law of ash composition , in advance to judge the coal forming environ-ment.

其原理是：灰成分与煤中矿物质种类与含量具有成因上的相关关系--据端元特征，可以判断介质的总体运动方向；由CaO-Mgo端元特征，可以判断泥炭沼泽受海水影响的程度；由端元特征，可以判断聚煤环境的氧化还原条件。
