(1)   It should have high calorific value.

(2)   It should have low moisture content.

(3)   It should have low ash  content

(4)   It should have high calorific intensity. (Calorific intensity-maximum temperature attainable on complete combustion of coal with theoretical amount of air.)

(5)   Size of coal should be uniform.

(6)   Coking quality should be high (coal on heating gives a coke which is porous, hard, strong. And  suitable for metallurgical needs, then the coal is known as caking coal)
