摘要:

为研究炼焦煤在不同粒度下的性质,对炼焦煤矿点赵各庄肥煤、海菱1/3焦煤、穆村焦煤、三给贫瘦煤进行了筛分,分别过10mm、5mm、3mm、1mm标准筛,通过对不同筛分粒级的单种煤进行煤质分析和煤岩分析,研究了不同煤种、不同筛分粒级对炼焦煤性质的影响,为单种煤选择性粉碎工艺提供了一定的理论依据。

Abstract:

In order to study the properties of coking coal at different grain sizes,Zhaogezhuang fat coal,Hailing 1/3 coking coal,Mucun coking coal and Sangei lean coal are screened by 10mm,5mm,3mm and 1mm screens.Coal quality analysis and coal petrography analysis are carried out for each individual coal at different grain sizes.Influence of coal kind and coal grade to coking coal property is studied,which provides certain theoretical basis for selective crushing process of individual coals.
