The Actual Difference Between Surface and Underground Mining

Surface mining can be accomplished by the following main methods: 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:
