霍林河煤田宏观煤岩类型划分及煤岩特征

The Division and Features of Macroscopic Coal Petrography of Huolinhe Coalfield

主要应用煤岩学方法,根据霍林河煤田煤的宏观煤岩特征,提出了老年褐煤宏观煤岩类型的划分方案,并总结了主要可采煤层的宏观煤岩特征和不同类型煤的分布规律,进而阐述了成煤泥炭沼泽不同环境交替出现的演化历程。

According to the features of macroscopic coal petrography of Huolinhe Coalfield proposes a division programme of macroscopic coat petrography of ancient brown teal by the means of coal petrography, and concludes the macroscopic coal petrography features of coal seam which can he mainly explored and the distribution laws, of different coal and expoundes the evolutionary process of peat moss than appers in different environments alternatively.
