Mining and its Types

What is the difference between surface mining and subsurface mining?

• Surface mining is used for extracting minerals from deep underground, while subsurface mining is used for extracting minerals from the surface of the earth.

• Surface mining is more environmentally friendly than subsurface mining.

• Surface mining is done on the surface of the earth, while subsurface mining is done below the surface of the earth.

• Surface mining is done underwater, while subsurface mining is done on the surface of the earth.

Name two types of surface mining.

• Strip mining and open-pit mining

• Shaft mining and borehole mining

• Drift mining and slope mining

• Underground mining and tunnel mining

What are the environmental impacts of open-pit mining?

• Preservation of natural habitats

• Increase in biodiversity

• Improvement in air quality

• Deforestation, habitat destruction, and contamination of soil and water

How does placer mining differ from hard rock mining?

• Placer mining uses heavy machinery to extract minerals from loose sediments.

• Placer mining involves extracting minerals from underground rock formations.

• Placer mining involves extracting minerals from loose sediments.

• Hard rock mining involves extracting minerals from loose sediments.

What is the process of solution mining?

• Pumping water into underground deposits to extract minerals

• Using a solution to dissolve minerals from underground deposits

• Using explosives to extract minerals from the ground

• Using mechanical equipment to dig minerals from the earth

Explain the concept of strip mining.

• Strip mining involves planting trees in a straight line.

• Strip mining is a type of dance move popular in the 1980s.

• Strip mining is a method of extracting minerals from underground caves.

• Strip mining involves removing a layer of material to access the desired resource.

What are the dangers associated with underground mining?

• Risk of falling rocks

• Risk of cave-ins, explosions, and exposure to harmful gases

• Injuries from heavy machinery

• Exposure to extreme temperatures

Describe the process of mountaintop removal mining.

• It involves planting trees on mountain slopes

• It is a process of building ski resorts on mountain peaks

• It is a method of conserving natural habitats on mountain ridges

• It involves the topographical alteration and/or removal of a summit, hill, or ridge to access buried coal seams.
