EVERYDAY SCIENCE

Detailed explanation-1: -Strip mining is used where coal seams are located very near the surface and can be removed in massive layers, or strips. Overburden is usually removed with explosives and towed away with some of the largest vehicles ever made.

Detailed explanation-2: -Explosives are used to fracture any overlying rock, and then heavy machinery is used to remove the overburden and dump it into a nearby area. Mining is done in long, narrow strips, thus the name “strip mining”.

Detailed explanation-3: -strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral.

Detailed explanation-4: -Strip Mining: Layers of soil and rock overburden are removed the coal exposed coal seam is excavated. The area is then backfilled, regraded, and replanted during the reclamation process.

Detailed explanation-5: -Strip mining removes a thin strip of overburden, (meaning soil or earth) from the desired deposit, then, the overburden behind the deposit is dumped and the desired deposits extracted.
