摘要
研究了华亭矿区5号煤层煤岩煤质特征,对其成煤植物、成煤环境、古气候变化进行了综合分析;在此基础上,结合微观煤相标志,划分了5号煤层煤相,共划分出6种煤相类型:陆地苔藓沼泽相;浅覆水—滞流森林沼泽相;中等覆水—滞流森林沼泽相;深覆水—滞流森林沼泽相;浅覆水—滞流草木混生沼泽相和开阔水域沼泽相。并对5号煤层煤相类型在垂向上的演化规律及影响该煤层煤相变化的因素进行了初步分析。
After studied No.5 coal seam lithologic and coal quality characteristics in Huating mining area, comprehensively analyzed coal-forming material, environment and palaeoclimate, on this basis combined with micro-facies markers divided 6 coal facies types for No.5 coal seam. They are land aphagniopratum facies; shallow water covered-stagnant forest bog facies; medium water covered-stagnant forest bog facies; deep water covered-stagnant forest bog facies; shallow water covered-stagnant swamp facies and wide water covered swamp facies. The paper also preliminary analyzed facies types of No.5 coal vertical evolutional pattern and influencing factors.
