A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.

Mar 09, 2018· Selecting a Mining Method. is a variation of room-and-pillar mining in which the footwall of an inclined ore body is adapted for use of trackless equipment. Open pit mining method works best when the deposit is close to the surface as it is way more economical to use this method instead of underground mining. Open pit mining operations
Jul 21, 2016· Caving methods of mining are varied and versatile and involve caving the ore and/or the overlying rock.Subsidence of the surface normally occurs afterward. Longwall mining is a caving method particularly well adapted to horizontal seams, usually coal, at some depth. In this method, a face of considerable length (a long face or wall) is maintained, and as the mining progresses, the overlying
