MINING METHODS |authorSTREAM

Coal is mined by two main methods : Underground or 'deep' mining Surface or 'opencut' mining The choice of method is largely determined by the geology of the coal deposit, in particular the depth of the seam below the surface. The majority of the world's coal reserves are recoverable by underground mining.
