Types of Mining

Surface Mining

Strip mining is that all of the land in a certain direction is mined. This creates an artificial steppe effect on the land and it becomes polluted and the water is poisoned.

Open Pit mining is when the earth is mined into a certain area and roads are carved into the earth. The area is open to the air causing pollution and destroying all of the land used for the mine.

Mountain Top Removal is when the tops of mountains are mined or exploded off and the resources with in are extracted. The environmental effect is massive with entire mountains be being destroyed and entire ecosystems destroyed.

Subsurface Mining

Slope: A method of accessing valuable geological material like coal or ore. Sloping shafts travel downwards towards desired materials. In slope mining, the primary access to the mine is on an incline. The environmental impact is that the water table can be effected and the areas around the mine could be polluted

Drift: The mining of an ore deposit by underground methods. A drift mine is an underground mine in which entry or access to the mine is above water levels and generally on a slope of a hill. The environmental impact is that the water table can be effected and the areas around the mine could be polluted.

Shaft: Shaft mining, also known as shaft sinking, refers to the method of excavating a vertical or near-vertical tunnel from the top-down, where there is initially no access to the bottom. The environmental impact is that the water table can be effected and the areas around the mine could be polluted.

Fracking

How? Water, sand and chemicals are pumped into the ground fracturing shale and freeing gas from fissures.


Environmental Effect? Earthquakes may occur from the process. Many chemicals, sand and water are pumped into the earth where they don't belong and could mess with the water table
