What Is The Difference Between Subsurface and Open Pit Mining

Difference Between Open Cast Mining And

Differences between open pit and underground mining Main Difference. In surface mining, the ore is accessed directly from the Earth's surface, and contact is maintained with the surface throughout the operation. Underground or subsurface mining is accomplished with the help of tunnels going into the Earth, and does not occur on the surface

The Actual Difference Between Surface and

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

What are the differences between open pit mining

Strip mining and subsurface mining Strip mining (or surface mining) is performed when surface soil and rock are stripped off to reach the mineral of concern. When such operations are done, surface water bodies (lakes, streams, etc) gets acidity. Acid mine drainage occurs when water molecules infiltrates the spoil banks. The water reacts with sulfide minerals to produce sulfuric acid.

But briefly, strip mining is economically "necessary" to extract some mineral resources, such as coal, when the overburden is not too thick. In such cases, an underground mine would be costly and probably unsafe.

AP Environmental Science Chapter 15 Flashcards

Subsurface mining is the extraction of mineral and energy resources from deep underground deposits. There are two kinds of surface mining, open-pit surface mining and strip mining. Iron, copper, stone, and gravel are usually extracted by open-pit surface mining, in which a giant hole is dug. In strip mining, a trench is dug to extract the minerals.
