Coal Types, Formation and Methods of Mining - epcamr.org

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 often be produced from the mine's highwall by the use of augers or highwall miners. Open pit mining is usually found where coal seams are thick and can reach depths of hundreds of feet.
