Surface Mining vs Subsurface Mining
Types of Surface Mining
In OPEN PIT mining a literal, open pit is used to extract rocks and minerals. Open pit mining can cause erosion to take place and sinkholes to form.
In MOUNTAIN TOP REMOVAL the tops of mountains are blown off and the excess is dumped in nearby valleys. The landscape must be restructured in order to reach the strip of coal. Mountain Top Removal can destroy forests and bury streams.
Types of Subsurface Mining
In DRIFT mining, deposits of valuable materials are accessed underground, through entries above sea level. Drift mining can cause erosion of soil on top of the access entry, without layers of support underneath it can wash away easily.
In SHAFT mining, is the extraction of valuable minerals through a vertical tunnel starting above the surface of earth.
