Study on the Whole Process Intelligent Mining Architecture and Key Technologies of Open-pit Mines
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 archi-tecture 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 unloa-ding was designed,and the multi-link and serialized key technologies of intelligent mining,including intelligent perception of e-quipment 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 tech-nologies have been demonstrated and applied using the 3D simulation system,intelligent command and dispatch system,and re-mote control system of drilling rigs in the intelligent production of Qidashan Mine as examples.In the end,intelligent safety ap-plications 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 intelli-gent construction of open-pit mines in China.
