Abstract: Jet control systems are widely used to solve practical tasks in many industries, including mining and transportation of liquid and gaseous hydrocarbons. Unlike traditional ejectors, the use of a multi-flow reversible ejector opens up unique opportunities for the efficient distribution of energy across different channels and in any direction within a three-dimensional space. The article discusses options for the jet control systems that use a rotating nozzle and intelligent nozzle devices with the application of the CFD technology. The authors of the article propose new scientific principles of designing a multi-flow reversible ejector with controlled energy distribution across the ejector channels, including the use of a rotating diffuser in an upgraded de Laval nozzle. The results of the performed studies are mainly used to promote scientific research and development activities in creation of energy-efficient oil and gas production technologies. Some of the research results can be used in developing promising robotic equipment for various purposes.The results of the study show that digitalization leads to a 21.4% reduction in the share of workers in traditional jobs, while the demand for IT specialists grows by 285% and that for operators of robotic systems by 156%. The economic efficiency ratio of digitalization is 2.12, and the return on investment period is reduced from 7.8 to 4.2 years. A positive correlation has been established between the level of digitalization and the labour productivity (r = 0.821). The theoretical significance of the work lies in developing conceptual ideas on transformation of labour relations in the digital economy in specific conditions of the mining industry. The practical value is defined by the possibility of using the obtained results for strategic planning of the human resources development and optimization of the investment decisions in the field of digitalization of coal companies.
