Abstract: By establishing a distributed high complexity C/S architecture, coding CAD/GIS plug-in to achieve the export function, and based on the interactive visualization platform of 3D spatial data, 3DGIS platform was developed, and the virtual mine simulation platform was built by combining VR technology. The results show that the virtual mine simulation system can classify the internal operation program, separate the external display operation from the internal logic operation, and the system operation delay is low, efficient and stable. The system has a strong vertical transfixtion ability of spatial data and realizes the integration of different dimensional data. The system has unique advantages in dynamic visualization of mine objects. On the basis of restoring various physical and geographic information of mines, it can be independently set and select the information of simulated scenes.
