Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverableThis is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining The particular characteristics of the coal mining industry create unique .
Mine development Coal can be extracted from the earth either by surface mining or underground mining In open-pit coal mining, a pit is dug in an area and this pit becomes the open-pit mine, sometimes called a quarryOpen-pit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting becomes too great
Also known as “soft coal”, bituminous coal is the type found in Cape Breton and is our most abundant fuel It is greatly used in industry as a source of heat energy Anthracite – Stage Four Anthracite, the fourth stage in coal formation, is also known as “hard coal” because it is hard and has a high lustre
Finite resources entail a finite mining life cycle As coal reserves in a mine are removed or become uneconomical to continue mining, reclamation activities will replace removed soil and/or substrate materials and revegetate the mine in an effort to (1) return it to as close to natural state as possible or (2) redesign landforms to allow .
