摘要
通过双鸭山盆地煤田煤系的含煤性、阐述了煤层煤质特征及变质规律,确定该区煤种以气煤为主,长焰煤、焦煤次之,瘦煤、贫煤、无烟煤和弱粘结煤较少。煤的变质程度呈现一定的规律,即水平方向上呈带状分布,垂向上分带不明显。
through the introduction of feicheng coal coal-bearing basin,expounds seam coal characteristic and the coal metamorphism law to give priority to,long-flame coal gas,coal,coke,thin and weak depleted coal,anthracite coal binder.The coal metamorphism presents certain laws,namely the horizontal and vertical distribution of ribbons no obvious zoning
