| 摘 要： | 将黏结指数70～75的蒋庄矿1/3焦煤与黄陵气煤及田庄矿1/3焦煤进行了工业指标、煤岩组分及单种煤成焦显微结构分析。结果表明:蒋庄矿1/3焦煤变质程度低、挥发分高,成焦显微结构含有大量的各向同性结构,其煤质显示气煤特征。利用蒋庄矿1/3焦煤与黄陵气煤参与配煤炼焦,并对配煤质量和焦炭结构性能进行了研究比较。研究表明,蒋庄矿1/3焦煤与黄陵气煤对焦炭质量的影响较一致,当其配比较低时,焦炭质量较优,但当其配比按常规1/3焦煤比例配用时,焦炭质量劣化明显,进一步表明蒋庄矿1/3焦煤按气煤配用更为合理。

| Abstract: | The 1/3 coking coal and gas coal from Jiangzhuang Mine as well as the 1/3 coking coal(caking index ranging from 70~75),from Tianzhuang Mine were applied to the micro structural analysis on the industrial index,coal and rock components and signal coal coking.The analysis showed that the 1/3 coking coal from Jiangzhuang Mine had a low metamorphism degree;high volatile matter,coke misconstrue with lot different isotropic structure.The coal quality had the gas coal features.The 1/3 coking coal and gas coal were... |
