Mine Mining Basics Open Cut Coal. Open cut or surface mining in coal is a suitable choice when coal seams are closer to the natural surface. It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration. 2) Geological Modelling. 3) Mine Design.
