Abstract: In response to the three major difficulties in system planning,system intelligence,and system collaboration in the current intelligent construction process of large metal open-pit mines,study and application of the intelligent mining architecture and key technologies for the entire process of large metal open-pit mines have been carried out. Based on the entire process flow of intelligent and safe mining in large metal open-pit mines,an overall architecture of intelligent mining in large metal open-pit mines,including "three platforms,four levels,and four plates" was constructed. A full process intelligent and safe mining framework for five production processes,namely perforation,blasting,mining and loading,transportation,and unloading was designed,and the multi-link and serialized key technologies of intelligent mining,including intelligent perception of equipment status and operating environment,intelligent navigation and equipment behavior planning,and intelligent equipment core control are proposed. The study results have been successfully applied to Qidashan Open-pit Iron Mine,and relevant technologies have been demonstrated and applied using the 3D simulation system,intelligent command and dispatch system,and remote control system of drilling rigs in the intelligent production of Qidashan Mine as examples. In the end,intelligent safety applications with multiple scenarios,links,and processes were achieved in Qidashan Mine,forming a large-scale metal open-pit intelligent mining model of "full process planning,multiple operation intelligence and multi-scene linkage". This solves the key common theoretical and technical difficulties of intelligent open-pit mining,and has certain reference significance for the intelligent construction of open-pit mines in China.
