  • The Actual Difference Between Surface and Underground Mining

    Open-pit Mining: Removing ore to leave a crater. Quarrying: An open-pit mine for construction materials. Strip Mining: Ore is removed in parallel strips. Mountaintop Removal: Top of a mountain is blasted to remove deep ore. Dredging: Ore is removed from a river bottom. The main methods of underground mining are: Room and Pillar Mining: Removing ore, while leaving behind some for roof support.

  • Equipment Selection for Surface Mining: A Review

    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.
