Using 3DGIS, BIM and virtual reality technology, a virtual open mine 3D visualization application is constructed based on mine geological survey data and 3D model. It can display the comprehensive dynamic working conditions of production and safety in a hierarchical and real-time manner, and realize the patrol inspection of the main buildings, roads and greening in the industrial square and the dynamic information management of underground coal seams, faults, roadways, boreholes, tunneling and fully mechanized mining. The system serves the geological survey, mining, ventilation, safety, electromechanical, monitoring, dispatching and other specialties of the coal mine, realizing the integration and interaction of safety monitoring, personnel positioning, industrial video, integrated automation and other real-time data with the digital twin model in the virtual reality environment, and provides a strong guarantee for coal mine safety production management.
