Purpose. The research purpose is to develop and adapt the existing scientific-methodological, as well as software and information base for managing the geotechnological complexes to implement the process approach at the level of design and operation of mining-and-transport complexes during opencast mining. The development is associated with the coverage of more and more relevant options for excavating-conveying, as well as excavating-automobile-conveying mining-and-transport systems used in quarries. Methods. The methodology for managing the geotechnological complexes involves an adequate step-by-step accounting and appropriate operational regulation of all the main factors in specific mining-engineering, mining-geometrical, mining-and-geological, economic and organizational conditions. The method of simulation logical-statistical modelling of mining-and-transport processes is used as the main method. Findings. The results indicate that simplified analytical approaches and inadequately considered factors that have a significant impact on the efficiency of mining operations lead to significant errors (10-20% or more) that determine the real practical profitability of the mineral deposits development. Originality. Scientific novelty is an integrated approach to a single research object, which is a geotechnological complex, a unique simulation logical-statistical modelling of mining-and-transport processes, the economics of process management, as well as integrated and corporate process management. Practical implications. The obtained results of an integrated technical and technological audit of a project for mining the coal deposit, with sufficient accuracy for practical application, will ensure the methodological base development for the designing, planning and management of mining and mining-transport operations, as well as an increase in the efficiency of scientific and scientific-practical research in this direction when solving the practical tasks of mining sector.
