| Application of 3D Visualization Technique for Ore Deposit and New Geophysical Technology to the Exploration of Mine Substitution Resources:A Case Study of the Tongling-Shizishan Ore Field |
| Large quantities of geological and geophysical data are usually accumulated in the course of mine exploration.With the development of the 3D visualization technique for geological bodies and the new data-processing method for geophysics,these data can play an important role in the substitution resource exploration through refining usable information from the old data,thus avoiding repeated work.With the Tongling-Shizishan ore field as a study area,the authors collected the geological and drilling data accumulated in various exploration phases and adopted 3-D visual geological body modeling method to set up its 3-D deposit model.The relationships between geological attributes and ore bodies were analyzed under a visual environment.Based on the analytical results,the authors delineated a new target area called Qianchong in search for the same type of ore deposits,and this discovery was later verified by such geophysical methods as the EH-4 technique.The drilling results have proved that the re-exploitation of old data can not only provide more information for substitution resource exploration but also save funds and time. |
