Environmental Contamination From Trace Elements In Coal The general conclusion from these studies is that coal cleaning represents a viable shortterm solution to providing a lowash and lowsulfur coal the newer preparation plants can recover about 90 of the btu content of coals while reducing medium Apr 11, 2017Here Are the Advantages of Coal. 1. It is available in an abundant supply. Industrialized countries, including the United States, India, China, and Russia, have a large amount of coal that is available to them. Some estimates have the US holding enough coal that has already been mined to fuel current resources for the next 400 years. On the other hand, to extract deeper coal deposits, underground mining is the only choice. Opencast mining can be used to extract almost 90% of the coal deposits. For this, the overburden of rock and soil is broken open with explosives and removed to expose the coal seam underneath. The coal deposit is then drilled, fractured, and mined in strips.
