Coal Types, Formation and Methods of Mining - epcamr

Surface mining is accomplished by removing overburden from the coal seam and then blasting and removing the coal. The ratio of overburden excavated to the amount of coal removed is called the overburden ratio. The lower the ratio, the more productive the mine. The lowest overburden ratios are found in western surface mines. Often more than one coal

The Actual Difference Between Surface and Underground

Underground mining is used for gold, platinum, zinc, lead, and increasingly, coal. As can be seen, surface mining is much more advantageous than its counterpart. However, when an outcropping ore body stretches deep inside the Earth, surface methods can be used to begin the mining operation, which then need to be continued further by underground mining.

What You Should Know About Metallurgical Coal

21/08/2020  Metallurgical coal differs from thermal coal, used for energy and heating, by its carbon content and its caking ability. Caking refers to the coal's ability to be converted into coke, a pure form of carbon that can be used in basic oxygen furnaces. Bituminous coal—generally classified as a metallurgical grade—is harder and blacker. It contains more carbon and less moisture and ash than
