Abstract: Mined-out area survey as the part of mineral resource exploration played an important rule in recovery of mined-out area and mine safety control.The grasp of mined-out area shape and the distribution of solid minerals in mined-out area is the important basic work for mineral management.Based on the real survey data of mine area，the key technology of mined-out area 3D modeling visualization is introduced.With the help of mineral reserves evaluation and iExploration-EM of 3D modeling system，the development of mined-out management model is realized.In combination with the 2D geological information management，a good effect is obtained by adopting the transparent mineral entity model and 3D mined-out area entity model under the same situation.
