Mining support companies are increasingly opting for 3D modeling technologies which reduce costs of discovery, improves prospecting and facilitates focused exploration. A geological 3D modeling tool provides computerized illustrations of earth crust based on geological and geophysical observations made on earth surface and earth crust. It also provides detailed mapping and visualization of structural data of prospective mining zones and supports companies in resource estimation of mines, thus aiding the stakeholders to better interpret the data .This technology enhances discovery efficiency and improves exploration success rate.  For instance, BRGM, a leading geological exploration based in France, carried out 3D geological modeling at Gardanne coal basin.
