The development of digitalization and information technology opens up new opportunities to improve the efficiency of solid mineral deposit development. In the mining industry, the greatest potential lies in open-pit mining, which uses high-tech mining and transport equipment, which is currently undergoing a transition from diesel engines to gas-diesel, gas and electric ones. The purpose of this article is to design and develop the scientific and methodological potential of analysis, evaluation and optimization of the functioning of geotechnological complexes at open-pit mines. Realization of the set goal is carried out on the basis of the process approach in management of geotechnological complexes with the use of methodology of the in-depth analysis of factors and interrelations of all subsystems and elements. Scientific and practical novelty of the research lies in the development of simulation models with the main mining transport equipment using electric and diesel engines, but also gas-diesel and gas engines, as well as the development of methodological aspects of complex technical and technological audits of mining enterprises. The developed direction ensures the realization of the existing potential for improving the efficiency of geotechnological complexes, including economic and environmental aspects.
