Abstract：The slightly-caking coal produced by the Huangling Mining Corporation in Shanxi is largely sold as steam coal at the present, which not only adversely affects the economic efficiency of the enterprise, but also is a waste of the resource. Systematic investigation was carried out for the physico-chemical properties of Huangling slightly-caking coal and the feasibility of its injection into the blast furnace was explored. The results demonstrated that Huangling slightly-caking coal has a number of advantages and therefore fully meets the basic requirements of coals used for blast furnace injection. Its drawbacks such as lower igniting points, relatively strong explosivity, having certain extent of caking ability and poorer grindability can be dissolved by means of mixing it with anthracite and lean coals. Upon the ranks of coal to be mixed with, the blending ratios of Huangling slightly-caking coal should not exceed 30 to 50%.
