coal exploration methods

Coal Exploration - an overview ScienceDirect Topics

Coal exploration activities to discover coal reserves include creating a geological map of the area, carrying out geochemical and geophysical surveys and exploration drilling. The mining operation only begins if the coal can be economically recovered. As per the BP statistical review, the world coal reserves are estimated to be 1035 × 10 9 t (1035 billion tonnes) [2].
