Coal beds consist of altered plant remains. When forested swamps died, they sank below the water and began the process of coal formation. However, more than a heavy growth of vegetation is needed for the formation of coal. The debris must be buried, compressed and protected from erosion.

Coal preparation. As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions.In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for the equipment and miners.
COAL - Earth Science
Strip mining is the process of scaping the coal from the top surface of the ground. The problem with peat is that it has a very low heat value per kilogram of the fuel burned. In addition, strip mining is ecologically very destructive unless the mining company makes a conscious effort to restore the country side.

Once a seam has been discovered, considerable further work is ...
Coal Mining - an overview | ScienceDirect Topics
Coal mining, particularly in the case of open-cut mines, requires that large areas of land are temporarily disturbed, and perhaps withdrawn from other productive uses such as agriculture, while the process of coal extraction is under way.The land may, however, be returned to productive use after mining or even while mining in other parts of the area is still in progress (Figure 1.2).
