OPEN CAST MINING. METHOD Open Cast Mining Method Open cast mining is a surface exploitation method, used mainly for coal. It resembles open pit mining but differs in one unique respect: The overburden is not transported to waste dumps for disposal but cast or hauled directly into adjacent minedout panels.. Continued OC Mining is subdivided into two methods i. . Strip Mining Mi
Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
