The paper deals with impact of surface cost on lignite mining project. Not only profitability is discussed but also relations between land owners and a Mine Company.
Coal ore extraction involves both surface (openpit) and underground mining techniques. The method selected depends on a variety of factors, including the nature and location of the deposit, size, depth, and grade of the deposit (Norgate and Haque, 2010).Surface mining operates in two distinct stages, overburden removal and coal extraction, as well as the recovery of the mined area.
COAL MINING METHODS. In 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,...

Mining coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are dynamited and removed to access coal seams.
