Abstract：The ash of coking coals is an important factor to determine its costs. To compare the influence of ash on coking property of different coking coals from the same mine， the caking property ， the maceral property， the ash of coking coals and the quality of cokes on 40 kg poilt coke oven were analyzed. With the decrease of ash content of different coking coals， caking property is improved by different degree. Caking property of the coking coal with a better caking property has a little improvement； but caking property of the one whose caking property is worse is improved obviously. Ash of different coking coals changes differently when its ash changes. With the decrease of ash ， the strength of cokes from different coking coals has different changes. The strength of cokes from coking coals whose caking property is better has a little change， but the strength of cokes from coking coals whose caking property is worse has much improvement.
