    Coal mining companies are making considerable efforts to rehabilitate the landscape after open cast mining, recreating natural contours, returning the top soil, sowing grasses and controlling erosion. The ultimate aim of these efforts is to return the land to a state where it can be used again, either for agriculture or grazing [1].Coal in the opencast operation, the planned annual production wasincreased from 8to8,5million tons of coal. It will be noted that this increased demand is than compensated forinthe improved extraction rate. The increased demand amounts to 30xO,5=15 million tons, while the increase inextractable coal is 338,5-259=79,5 million tons.
