摘要
采用煤岩学方法,对宁东煤田中部2号煤煤相特征进行了分析,研究结果表明2号煤层属于淡水陆相沉积,其成煤植物以草本植物为主,煤相类型以低位泥炭沼泽相为主、潮湿森林沼泽相为辅。通过煤相分析,为宁东煤田中部2号煤成煤环境的研究提供了佐证。
The coal petrological characteristics of the No.2 coal seam from Ningdong Coalfield Central was studied with the method of coal petrography. The results indicated that the No.2 coal was fresh continental deposits and its coal-forming plant was mainly dominated by herbaceous plants. The main moor type was low peat moor, while moist forest moor was subsidiary. Through analyzing the coal facies, evidence for the study of coal-forming envirment in the No.2 coal seam from Ningdong Coalfield central was pvovided.
