构造煤成因-结构-构造分类新方案

New genetic-texture-structure classification system of tectonic coal

借鉴构造岩的分类方法和前人的研究成果,依据构造煤的成因、结构和构造,提出了一套既适合煤矿瓦斯灾害防治又适合煤层气开发的新的成因-结构-构造分类方案,将构造煤划分为脆性变形和韧性变形2个变形序列8个煤类,其中,脆性变形序列的构造煤又进一步划分出片状序列和粒状序列,同时,重新厘定了不同类型构造煤的变形性质和结构、构造特征.

Based on the cause, texture and the structure of tectonic coal, used the method of fault rock classification and the achievement existed for reference, the new genetic-texture-structure classification system was put forward, which was suitable for both the prevention of the coal mine gas disaster and exploitation of coal bed gas, tectonic coal was divided into two series of brittle and ductile deformation and eight types, especially, the brittle deformed tectonic coal was divided into flake-like and granular array, moreover, the character, texture and structure of different types of tectonic coal were given again.
