淮南谢二矿煤的后生破碎与煤的显微组分关系研究

The Relation Between the Secondary and Coal Maceral of Coalbeds at Xiejiaji Coal Mine No.2 in Huainan Coalfield

本文以淮南谢二矿为例，对煤的后生破碎与煤的显极组分之间的关系进行了研究，研究表明：①煤的物质组分是影响煤后生破碎的内在因素；②物质组分含量变化大的煤层，其后生破碎程度一般较高；③构造煤的形成与物质络分有关；均质镜质体会量高、基质镜质体含量低的煤易于破碎。

This paper studies the relation between the Secondary coal breakage and coal maceral of coalbeds at Xiejiaji Coal Mine No.2 Huainan Coalfield。 reveals that:1.Coal maceral is one internal factor affecting secondary 2.Usually,the more the changs of the contentes of coal maceral, the secondary coal breakage of coalbed。3.Coal with more telocollinite and less desmocollinite is prone to break。
