| 摘 要： | 从宏观和微观两方面对不同变质程度煤所形成焦炭的结构、构造进行了深入研究。从气煤到肥煤阶段（Ｒｏ，ｍ：０．７７％～１．１６％），焦炭气孔壁厚度逐渐增大；进入焦煤阶段（Ｒｏ，ｍ＞１．１６％），焦炭气孔壁厚度降低。气煤、１３焦煤形成的焦炭结构以各向同性体为主，焦煤、肥煤炼出的焦炭以粒状镶嵌结构为主。由气煤和高变质程度的焦煤形成的焦炭，其气孔以微孔和大孔为主，气孔分布标准差Ｄｓ最大；肥煤炼出的焦炭，其气孔分布大小较均一；１３焦煤和低变质程度的焦煤成焦后，气孔分布状况介于上述二者之间

| Abstract: | In order to reveal the relationship between metamorphic degree of coal and coke characteristics, authors carried out coking test on some raw coal of Beijing Coking Factory. Texture of coke formed from gas coal is mainly isotropic, while coke formed from fat coal and coke coal mainly displays granular mosaic texture. Vesicles distribute homogeneously in coke formed from fat coal. When vitrinite reflectance ( R o,m ) reachs 1 16%, thickness of vesicle mural is maximal. |
