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。
Based on the coal property of the coalfields in Shuangyashan Basin, the characteristics of coal seams and the metamorphism of the coal seams are expounded. It is determined that the coal seams are mainly gas-fired coal, long-flame coal, secondary coking coal, lean coal, lean coal, anthracite and weakly viscous Less coal. Coal metamorphism showed a certain degree of law, that is, the strip was horizontal distribution, vertical sub-band is not obvious.
