What is Strip Mining? (with pictures)

Mar 15, 2019· Strip mining is a type of surface mining which involves the removal of a thin layer of material known as an "overburden" to access buried deposits of useful minerals. This type of mining is only effective in areas where mineral deposits are very close to the surface, making it feasible to quickly and easily remove the overburden to get to them.
