2 Types of Mining
Surface and Subsurface
Surface- when an ore bed is found relatively close to Earth's surface
-Strip - soil and rock are removed from the overlying surface (Destroys Landscapes and Habitats)
-Open Pit - extracting rocks and minerals from the Earth from a open pit (Release harmful substances into the soil, air and water)
-Mountain Top Removal - mining of the summit of a mountain (affects the streams that run through the valleys)
Subsurface- when ores are found thousands of feet below Earth's surface
-Slope - sloping shaft travels downward towards desired material (topsoil is eroded and stablilty of slope decreases)
-Drift - tunneling through Earth's surface ( waste that comes to the surface becomes toxic)
-Shaft - tunnel straight down into the Earth (produces greenhouse gas emissions)
Fracking- drilling into the Earth and try to release natural gases used as energy
(Contamination of Groundwater, Air pollution, waste disposal, and toxic waste deposition)
