摘要
选取常用炼焦用煤(1/3焦煤、肥煤、焦煤)测定其显微组分,活惰比,最大流动度,镜质组反射率,结果表明,1/3焦煤相对于其他焦煤含稳定组组分最多,肥煤矿物质含量最多;焦煤和1/3焦煤的镜质组反射率值界线分明,焦煤和肥煤的活惰比与镜质组反射率成正比,与最大流动度成反比,而对于1/3焦煤,该趋势不明显。
The main cokemaking coals （one thi,＇d coking coal, fat coal, coking coal） were selected to test their microtexture, the ratio of active constituent to inert constituent, the maximum fluidity and the reflectance of vitrinite. The results show that one third coking coal contains much more liptinite than other type of coal, fat coal＇s mineral content is the highest in three type of coals; coking coal and one third coking coal have evident borderline on reflectance value of vitrinite;the ratio of active constituent to inert constituent of fat coal and coking coal is proportional to the reflectance of vitrinite and inverse proportional to maximum fluidity. However, for one third coking coal, such trend is not so obvious.
