Purpose. To justify and develop the theoretical bases of the formation and operation of the container technology for moving mining mass from quarries, which ensures a reduction of economic and energy costs, as well as damage to the environment during the extraction of mineral resources. Methodology. The work used complex research methods, including analysis and scientific synthesis of scientific and technical information; theoretical research; methods of mathematical and computer modeling, and design developments. Findings. The analysis of existing technologies for open-pit mining and the current state of mining indicates an urgent need to develop new resource-saving technology and environmentally friendly technologies for moving rock mass for open-pit mining. A new technology for container transportation of rock mass in containers is proposed without the construction of additional transport communications in the quarry and has technological and energy-saving advantages. Originality. The scientific novelty of the research consists of an integrated and systematic approach to assessing the energy efficiency and environmental safety of the proposed set of equipment for container technology for transporting rock mass. Practical value. In this work, special attention is paid to the problem of the formation and effective use of a new resource-saving and environmentally friendly container technology for moving rock mass from deep quarries. These advantages are simultaneous excavation of rocks, transportation of rocks over the shortest distance, low container packing ratio, and mobility of a complex of lifting machines, which will reduce energy consumption and the cost of transporting rock mass. A transport complex has been developed to ensure the reliable operation of lifting and transport machines.
