The sooner and the more completely this happens, the more coal can be blown into the blast furnace and the coke rate can be correspondingly reduced and thus the pig iron production costs are reduced. The photos show impressively the earlier ignition and thus the optimized injection process when using the Oxycoal technology.

Underground coal gasification - Wikipedia

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an in-situ gasification process, carried out in non-mined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.
