Vehicle transportation is a key link in open-pit mine production. Traditional vehicle control in open-pit mines usually adopts manual patrol, walkie-talkie communication, fixed camera monitoring and other methods, which has problems such as poor real-time performance, difficult manual management, and untraceable driving trajectory, which cannot meet the current mine intelligent management requirements.With the development of 3D GIS and visualization technology, the combination of open-pit mine and 3D GIS can better display the geomorphological structure and other spatial environmental factors of mine. In this paper, based on Cesium, an open source 3D visualization framework, a vehicle control system for open-pit mine is constructed to model the 3D scene of mining area.And the real-time position, status, trajectory and other information of the mine car are intuitively presented on the three-dimensional map, so that the mine operators can better track and schedule the vehicles, and improve the efficiency of production operations.
