Abstract:The traditional open-pit mines face significant challenges, including information silos, data integration difficulties, poor information flow, and extensive management practices. These issues result in weak comprehensive capabilities for informatization, visualization, and intelligent management and control. To address these issues, this study proposes and practices an Integrated Intelligent Management System of Mines based on real 3D and artificial intelligence (AI) technologies. The system innovatively integrates real 3D with AI to construct a digital twin management and control platform. This platform centers on unified spatio-temporal benchmarks for full-element mine information integration. It establishes a coordinated management framework covering “human-equipment-material-environment” full-elements in open-pit mines and implements an integrated intelligent management system platform. This integrated system platform combines a “The Intelligent Mine Command Large-Screen System” with “The Multiple Demonstration Applications”, covering core aspects of mine safety and production. Practical application at the Dalucao Rare Earth Mine in Dechang County, Sichuan Province, demonstrates that the system delivers significant improvements: mine production efficiency increased by approximately 27.78%, management efficiency improved by 25%, safety risks were effectively reduced by about 40%, and annual labor costs were reduced by 1.2 million RMB. These results provide a replicable scientific paradigm for intelligent mine construction. The system holds significant importance for promoting the green, safe, and sustainable development of mineral resource exploitation.
