A 3-D Prediction Method for Blind Orebody Based on 3-D Visualization Model and Its Application

Based on the study of existing orebody predicting theories and using commercial 3-D geological modeling software, we established an integrated 3-D quantitative method and procedure for locating blind orebodies, based on 3-D visualization model. In this paper, we discuss the procedure of the 3-D visualization method, such as data preprocessing, 3-D geological modeling, process and 3-D quantitative prediction. Using the 3-D visualization method, we established favorable prospective targets, calculated the ore containing probability of perspective blocks and estimated the resources in a test project zone using the Gejiu tin deposit in Yunnan, China. This application shows that the 3-D visualization method is effective in 3-D orebody prediction for determining quantity, position and probability.
