Mining

By: Landon Stillitano & Maddie Rorie

Surface Mining

Surface mining is when the overburden is removed and is then blasted. From the blast, coal and other minerals are extracted.

Effects of Surface Mining

Destroys landscapes, vegetation, and wildlife. The removal of these plants lead to soil erosion.

Subsurface Mining

The extraction of ores and minerals from underground

Effects of Subsurface Mining

Hazardous acid, mine drainage, changes pH levels



Not much effect on surface but hazardous to miners

Fracking

Fracking is the use of pressurized water and chemicals forced into a hole to release natural gas. Some consequences are that it contaminates ground water, exposure to toxic chemicals, change in the climate, can cause water deficiency and fracking induced earthquakes.
