3 Methods of Coal Mining EzineArticles

3- Mountaintop Removal Mining: Mountaintop Removal Mining involves using a combination of Contour Mining and Strip Mining. The mountaintops are removed to expose the coal beneath and the coal is extracted. Underground Mining Methods. If the coal seams are too deep underground, then deep underground mining is necessary.
