以蒙古5号原煤为研究对象,对其基本煤质特征、煤灰成分、工艺性能、煤岩特征、浮沉实验及成焦特性等进行研究分析。研究结果表明,蒙古5号原煤属于特低全水分、中灰、中等挥发分、中硫分煤,煤灰的矿物质催化指数(MCI)较低,灰熔融性属于中等软化温度灰。强粘结性但有劣化表现,奥阿膨胀度较好,但吉氏流动度一般,有害微量元素含量低,但要注意氟的环境迁移;煤岩特性中活惰比为2.5,可满足焦炭反应后强度要求,原煤快速浮沉精煤三级回收率较好,焦炭反应后强度(CSR)为63.0%,各项异性成分含量为21.0%,能够满足我国进口炼焦煤的要求。

The Mongolia No. 5 raw coal was taken as the research object. The basic coal quality characteristics, ash composition, process performance, coal petrological characteristics, floating and sinking experiments and coking characteristics toward the object were studied and analyzed. The research results indicate that No. 5 raw coal shall be divided into ultra-low total moisture, medium ash, medium volatile matter and medium sulfur coal. The mineral catalytic index(MCI) of coal ash is relatively low, while the ash fusibility belongs to medium softening temperature ash. The object shows strong adhesion but signs of deteriorationat the sametime. Aoa expansion performed well but Giemy flow turned out to be on anaverage, level. Content of harmful trace elements is low, but attention should be paid to the environmental migration of fluorine. The active inert ratio of coal rock is 2. 5, which can meet the strength requirements after coking reaction. The rapid floating and settling of raw coal results in a better tertiary recovery rate for refined coal. The strength of coke after Coke Strength after Reaction( CSR) is 63. 0% . The content of various anisotropic components is 21. 0%, the coal can meet the requirements of China's imported coking coal.
