Energy advantages of container transport technology in deep careers

Purpose. To substantiate the rational parameters of a new container technology for moving rocks in quarries which has technological and energysaving advantages. Methodology. The work used a set of scientific research methods: scientific synthesis; technical and economic analysis of operating experience of transport systems; energy analysis of open pit mining processes; economicmathematical and multivariate analysis. findings. As a result of the completed design and technical and economic calculations, the rational parameters of the new container technology for moving the rock mass in the quarries were substantiated. originality. For the first time, a comprehensive analysis of the operation of transport systems in open pits was carried out based on an analysis of the structure and dynamics of energy consumption in deep pits. It was established that energy consumption for technological transportation in deep quarries ranges from 22-55 % for assembly transportation and to 85-90 % for trunk transportation in total energy consumption for mining rock mass. To improve the energy efficiency of transport systems of quarries, rational constructive and regime parameters of the new container technology in deep quarries are justified, which allows changing the principles of formation of excavators and transport complexes, increasing their productivity and energy efficiency. A method has been developed for calculating technical, economic and energy indicators of container technology for transporting rock mass, based on geoinformation modeling of the mining front and production facilities of deep pits. Practical value. Based on the established rational parameters of the new container technology, at the design stage, it is possible to make reasonable technical decisions that ensure the energy efficient operation of deep-pit transport systems.
