Обоснование условий применения автоматизированных систем управления открытыми горными работами строительства комплекса циклично-поточной геотехнологии в карьере с помощью имитационного моделирования

Abstract

The simulation modeling approach described in the article is intended to assess the efficiency of geo-technologies and can be applied: 1) to evaluate the implementation of smart geotechnologies with digital transformation of the mining systems; 2) to select the mining and transportation management system as well as the preferred logistic scheme of the mine. This approach makes it possible to make more reasonable investment decisions based on an objective quantitative assessment. Simulation modeling should be based on the results of geotechnical justification of structural parameters of the pit walls and benches in operating and limit states. Transition to automated systems to control smart geotechnologies in programmable mode and timely inclusion of the In Pit Crushing and Conveying (IPCC) technology into the transport scheme helps to: 1) remove people from the working zones inside the open pit; 2) significantly reduce the ore mining costs; 3) advance to a higher level of technology in developing the deposits; 4) process ores that were previously considered substandard. As an example, the assessment results are provided of the implementation of new rock mass transportation technologies at the Codelco copper mine in Chile in the Radomiro Tomic open pit.
