In view of problem that industrial configuration software cannot well process space information in current mine integrated automation system, a mine integrated automation system based on 3D visualization platform was designed. General structure of digital mine based on the system was given, structure of the system and implementation of data integration and data interface method between 3D visualization platform and integrated automation system were introduced in details. The actual application shows that the system realizes fine modeling of scenes of roadway, working face and underground electromechanical devices and improves modern management level of mine.
