The Actual Difference Between Surface and Underground Mining

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:

Coal mining Facts for Kids - Kiddle

Surface mining and deep underground mining are the two basic methods of mining. Seams relatively close to the surface, at depths less than approximately 180ft (50m), are usually surface mined. Coal that occurs at depths of 180 to 300ft (50 to 100 m) are usually deep mined, but in some cases surface mining techniques can be used.
