Abstract: The 3D digital mine information system is established in 2008 by Guangxi Gaofeng Mining company. Updating the 3D digital mine information system can provide guidance for prospecting and mining design and the dynamic production management work.Based on the Surpac software, the mine geological database is rebuilt, the 3D terrain model, 105^# ore body mining entity model and 3D model of the magmatic rocks and exploration engineering system are built combining the latest mine geological and surveying data. Besides that, application of some relative models are analyzed. The research results of this paper have great significance to provide guidance to the design of mining exploration and dynamic production management and improve the efficiency of the mine construction works.

Key words: Digital mine, Information system, Dynamic update, Surpac software
