Three-Dimensional Date Imaging in Mine Geology Applications

Simulations of complex physical phenomena, such as hurricanes and fluid flow around space vehicles, can now be effectively explored using modem visualisation techniques which have been developed to examine the results of numerical modelling using supercomputers. These techniques are also being applied extensively in medical investigations, including viewing the interior of the human brain. We have now applied these same techniques to the visualisation of gold deposits.Grade control in open pit gold mining operations may involve the collection of at least half a million samples in each mine. Extensive drilling programs also accompany the early reserve evaluation stages and exploration in advance of mining. Maximum utilisation of these very large amounts of information requires an ability to integrate, examine and present large three-dimensional data sets in order to be able to derive and effectively communicate information on grade distribution and geological controls.
