* Strip mining is a surface mining technique where layers of overburden (soil and rock) are removed to access the mineral deposit.
* Shafts are vertical tunnels dug deep into the earth, typically used in underground mining.
Here's how strip mining works:
1. Overburden Removal: Large machines remove layers of rock and soil that lie above the mineral deposit.
2. Mineral Extraction: Once the deposit is exposed, it is extracted using various methods, such as blasting or mechanical excavation.
3. Reclamation: After mining is complete, the land is often reclaimed to restore it to a usable state.
In summary: Strip mining focuses on surface extraction, while shaft mining involves accessing minerals through deep tunnels.
