Types of Mining

BY Natalie Fusaro and Airika Gales

Surface

Where soil and rock overlies the mineral deposit.



  • Strip Mining - to excavate by open cut methods.
  • Open Pit Mining - a type of surface mining where usually metallic minerals are removed.
  • Mountain Top Removal - Any method or surface coal mining that destroys a mountain top or ridge line.

Effects on the environment: Increased erosion, habitat destruction, air pollution.

Subsurface

The extraction of minerals from underground.



  • Slope - a method of accessing valuable geological material. Ex. coal, ore.
  • Drift - cutting and opening horizontally into the side of mountains allowing us to get to a mineral stream.
  • Shaft - A method of excavating a vertical or near vertical tunnel from the top down.

Effects on the environment: Can disrupt landscape underground, air pollution, can harm or kill mine workers, strips land of vegetation, soil and rocks, rainfall leaks toxic chemicals into the earth.

Fracking

A process of putting liquid into rocks at high pressure.


Effects on the environment: Puts chemicals in the ground, water pollution, air pollution near fracking sites from oil and gases, strains water sources from mass amounts being used, destroys streams and landscapes.
