Get PriceIn surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and transporting this fragmented overburden material (called spoil), (4) drilling and blasting the
Get PriceIn this process, coal and other ores can produce enough heat to melt ore, replacing coke completely (USEPA, 1995). In addition to reducing coke use, the DIOS process could cut the costs of molten iron production by about 10%, reduce emissions of carbon dioxide by 5 - 10% and increase flexibility by improving the starting and stopping capabilities of the steel mill (, 1994).
