What is Surface Mining? (with pictures)

Surface mining is a method of mining used to extract minerals and metals which are near the surface of the Earth There are three basic types of surface mining open pit mining strip mining and quarry mining These methods are much more economical than underground mining yet they can have a more significant impact on the surrounding environment unless efforts are taken to reclaim the land

Surface mining is done in five ways Strip mining – Strip mining is the most common surface mining method used to mine coal and lignite The process is done by removing a strip of overburden before mining a seam of mineral Strip mining is done only when the

When coal seams are near the surface it may be economical to extract the coal using open cut (also referred to as open cast open pit mountaintop removal or strip) mining methods Opencast coal mining recovers a greater proportion of the coal deposit than underground methods as more of the coal seams in the strata may be exploited

Room and Pillar Mining is Safe Efficient Environmentally Friendly Room and pillar mining is a non-subsidence plan for a mine preserving the precious farmland above It is among the safest and one of the most ecologically-friendly approaches to mining coal today creating a non-subsidence environment (no movement of land) and maintaining clean water standards

When coal seams are near the surface it may be economical to extract the coal using open cut (also referred to as open cast open pit mountaintop removal or strip) mining methods Opencast coal mining recovers a greater proportion of the coal deposit than underground methods as more of the coal seams in the strata may be exploited

Other types of mining including strip mining and speed mining should usually be performed in the same way they would if looking for ores However note that they must be performed 15 - 24 blocks below the surface as those are the only layers that fossils can generate in TNT mining can also be used and is often faster than digging with a tool but doing this method risks damaging and/or
