Smart Geology
Provide information services based on geological resource related data to achieve deep mining, sharing, and exchange of geological resource information.
The MapGIS Mine Management and Modeling System is a product developed by China National Land and Resources Corporation based on the "General Principles for Solid Mineral Exploration" (GB/T13908-2020) and the "Technical Requirements for 3D Geological Modeling of Solid Mineral Exploration" (DZT0383-2021). It integrates mine data management and modeling analysis for solid mineral resources using the MapGIS platform. With the powerful data management and modeling functions provided by the system, it can achieve 3D reconstruction, visualization expression, and 3D expression of attribute features of various geological bodies and geological structures. It can deeply analyze the spatial structure of geological bodies, provide 3D model data for mineral resource exploration, resource estimation, mineralization law research, mineralization prediction, mining and mine management work, and serve mineral resource exploration and development and mine management work.
