摘　　要：对贫瘦煤参与配煤的问题进行研究,通过对不同粒度贫瘦煤参与配煤炼焦所得坩埚焦热性能、结构强度、显微强度、成焦结构的分析,得出贫瘦煤的细粉碎有利于焦炭质量的提高,同时得出细粉碎的最佳粒度。Usage of meager-lean coal in coal blending is studied. By analysis on the technological parameters such as the thermal properties, structural strength, micro strength and microstructure of crucible coke acquired in the process of coal blending and cokemaking with different grain sizes of the meager coal it＇s concluded that fine grinding of meager coal is good to the improvement of coke quality and the optimal grain size of fine grinding is determined as well.

关 键 词：贫瘦煤 配煤 炼焦 细粉碎
