Types of Mining
Mining methods are classified based on location and techniques:
- Surface Mining: Extracting resources from the Earth's surface, including:
* Open-Pit Mining: Large pits used for materials like copper and gold. * Strip Mining: Removal of soil and rock layers to access coal or other minerals.
- Underground Mining: Accessing resources below the Earth's surface using tunnels or shafts.
- Placer Mining: Extracting valuable minerals from sediments in riverbeds or streams.
- In-Situ Mining: Using chemicals to dissolve and extract minerals without removing rock.
Types of Drilling
Drilling techniques vary based on resource type and depth:
- Oil and Gas Drilling: Extracting hydrocarbons using rigs and derricks.
* Onshore Drilling: Conducted on land for oil and gas deposits. * Offshore Drilling: Platforms in oceans to access underwater reserves.
- Water Well Drilling: Accessing underground water for domestic and agricultural use.
- Exploration Drilling: Identifying and evaluating resource deposits.
- Horizontal Drilling: Advanced technique to extract resources across a larger area from a single entry point.
