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].

Coal mining - Prospecting and exploration Britannica

Coal mining - Coal mining - Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered,

2019-3-26  One way of investigating these issues is through the application of Full Waveform Inversion (FWI) methods. To utilise the full power of these methods a high quality seismic dataset is needed. Such conditions are often met by 2D and 3D reflection seismic data acquired over coal seams in Bowen and Sydney basins.
