Abstract:Three-dimensional geological modeling can visually display and express complex geological bodies, which is conducive to showing the internal morphological characteristics of geological bodies and facilitating mine management and geological research. Taking an iron deposit as the research object, the relevant geological data in the region are collated and collected, and the data of the geological exploration line and drilling data of the production exploration line are processed by information technology. Based on the three-dimensional mining modeling software Surpac, the geological database, geological entity model and roadway model of the mining area are established. At the same time, the orebody model is established to provide the basis for delineating the effective mining boundary, and the local orebody model is established according to the model and the production exploration line data to compare and update the model. The establishment of the overall geological model provides technical support for the production and exploration process and provides guidance for the mining plan of the mine.
