本文就煤变质作用现分类中存在的一些问题,初步提出以煤变质的主导因素-热力为基准进行分类,划出了二类六型供商榷。又结合国情,分析了各类型情况。在此基础上,阐述河南禹县暨豫西煤田煤变质作用应属异常地温热变质类。
In this paper, some problems existing in the present metamorphism of coal metamorphism are initially proposed. Based on the thermal power of the coal metamorphism as the base, the second type and the sixth type are proposed for discussion. Combined with the national conditions, the analysis of various types of situations. On this basis, it is stated that the coal metamorphism in Yu County, Henan Province and western Henan coalfield should be abnormally warm and metamorphic.
