Coal Types, Formation and Methods of Mining
There are several types of surface coal mines. Area surface mines, usually found in flat terrain, consist of a series of cuts 100 to 200 feet wide. The overburden from one cut is used to fill in the mined out area of the preceding cut. Contour mining, occurring in mountainous terrain, follows a coal seam along the side of the hill. When contour mining becomes too expensive, additional coal can ...
