摘要
运用煤岩学和统计学的方法,对阴山矿区南阳坡6~#煤的样品进行研究。实验结果表明南阳坡6~#煤中的显微组分以镜质组(70.95%)占优,惰质组(21.24%)次之,壳质组(7.35%)含量较少。由此计算并绘制出GI-TPI煤相图和GWI-VI关系图及煤岩组分三相图等,通过这些煤相参数对6~#煤进行分析研究,得出结论:6~#煤的成煤环境为潮湿的还原环境,煤相类型为潮湿森林沼泽相,成煤植物具有木本植物亲和性。
Samples of No. 6 coal collected from Nanyangpo mine in Yinshan coalfield were analysed by using optical microscopy. The vitrinite（70.95%） is the most ingredient,low inertinite （21.24%） and liptinite （7.35%） in No.6 coal. Base on macerals data, GI-TPI, GWI-VI and three phases diagrams were drawn. The results indicate that the peat of No.6 was deposited in damp reducing environment, the coal facies of No.6 is in moist forest swamp, and coal-forming plants were mainly woody plants.
