抚顺煤田煤相研究

STUDY OF THE COALFACIES OF THE FUSHUN COALFIELD

本文通过对煤的宏观及微观分析、测定,依据煤相划分的标志,研究了煤层形成环境据此把抚顺矿区主要煤层划分为四种煤相,并解释了它们的形成条件。

Through study of the microlithotype and the maceral of the coal seams in Fushun Coalfield, four Coalfacies can be classified. precisely speaking, they are dry-strong oxidating forest swamp, shallowwater-Weak oxidating forest swamp, deepwater-strong reducing forest swamp and high ground watertable-forest swamp. They have some relationship with the watertable of the swamp on the one hand, and the subsidence scope of the basis during the forming of the individual coal seam on the other hand.
