This section describes the five main types of surface coal mining techniques: area mining, open pit mining, contour mining, auger mining, and mountaintop removal.Underground mining is also considered in this section.Terrain, economics, and custom generally dictate which technique an operator chooses.All surface or strip mining first removes the overlying vegetation, soil and underground .

Underground mining is the process of extracting minerals and ores that are buried too far underground to be mined using surface mining methods.Underground mines are the alternative to surface mines.Underground coal mines can drive 750 meters, uranium mines can reach 2 kilometres.Most underground mines bottom out at about 300 meters.
