The intelligent geological assurance system is built on the foundation of digitized mine geological data and automated geological exploration equipment. The system integrates advanced technologies such as GIS, digital twins, IoT, and big data to achieve high-precision modeling and transparent visualization of the mine's geological environment. Supporting both C/S and B/S architectures, the system employs key technologies including automated 3D modeling of complex geology, model mesh slicing, dynamic model updates, and massive data collection and management. It provides guidance and services for visualization and sharing of mine geological data, dynamic corrections, intelligent mining, intelligent excavation, intelligent management, safe production, and geological disaster early warning.
