  • Magnetic prospecting Articles

    Magnetic prospecting is a geophysical method based on the examination of magnetic field anomalies of the Earth caused by non-similar magnetization intensity of rocks. It is one of the methods of prospecting geophysics. Physical and geological prerequisites of this method implementation are based on magnetic dissimilarities of rocks, which form geological structures in the Earth crust.

  • 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, considerable further work is
