Abstract：Combined with coal quality analysis, laser particle size analysis and test of Hardgrove grindability index of the mixing coals, different ratio of mixing coals were investigated in Jinjitan coal and Lu'an coal.The results of the influence of Hardgrove grindability index of Jinjitan mixing coals showed that when added Lu'an good grindability coal to Jinjitan coal, the grindability of the mixing coal increased gradually with the increase of the ratio of Lu'an coal.After coal blending, it could prolong the service life of sample crushing equipment and expand the scope application of Jinjitan coal which was used for blast furnace inj ection.
