Qualification of employees who operate technological processes directly influences the safety of production. However, the employees’’ qualification cannot completely exclude human factor.
Today, there are many technologies that can minimize or eliminate human factor impact on production safety ensuring. The augmented reality technology is an example of this technology.
Nowadays, the augmented reality technologies and industrial technologies integration process moves to a new level of development. These technologies have huge experience, which has been accumulated in a long period of time. -This new level turns available by this experience combination and integration; it brings additional profit to the enterprise and can be a basis for completely new technologies. This paper shows an example of combination of augmented reality technology and oil pumps maintenance. For researching of efficiency of augmented reality system for oil pump maintenance, the laboratory unit with Grundfos vertical electric centrifugal pump (CR15-4 A-FGJ-AE-HQQE) was used. The laboratory unit is a physical model of one of the continuous oil processes. The oil pump of this laboratory unit is object of this research. The algorithm of servicing of oil pump was developed. The test of system and algorithms were carried out with four groups of people: the first one had only instructions to use on hand, the second one only used the internal recommendations of the system, the third one used only the help of an expert, and the fourth used internal recommendations and, if necessary, contacted the expert. The results show the efficiency and actuality of augmented reality technology for maintenance of industrial equipment, especially for the equipment operated in remote Arctic conditions.

This article examines the development of deep and extensive potash deposits, focusing on the mandatory preservation of the waterprotective layer and the implementation of measures to minimize surface subsidence, which significantly affects the mineral extraction ratio. These requirements, along with the need for disposal of processing plant waste, can be addressed through backfilling of mined-out spaces. The main types and methods of backfilling are reviewed. It is noted that backfill costs can be reduced by using technologies that employ hardening mixtures, which enable the subsequent extraction of inter-chamber pillars and increase overall mineral extraction. However, the production and complete filling of chambers with hardening mixtures substantially raises costs, limiting widespread adoption and necessitating the development of more economical solutions. A technology for layer-by-layer mechanized backfilling, developed by the Institute of Comprehensive Exploitation of Mineral Resources (IPKON) Russian Academy of Sciences, is presented. This approach involves two stages: the primary stage uses dry transport of processing waste, and the secondary stage backfills the upper part of the chamber with a hardening mixture prepared directly near the chamber, achieving high strength characteristics in the backfill mass. A proposed equipment set, designed to fit within the actual dimensions of mine workings, can be assembled into a single mobile system through technical modifications. The potential for using mobile systems to prepare backfill mixtures in underwater mining of solid minerals is also discussed.

Месторождения полезных ископаемых арктического шельфа территориально рассредоточены, удалены от централизованных источников электрической энергии и требуют для разработки автономные источники электроэнергии, не зависящие от поставок топлива, такие как ветрогенераторы или солнечные генераторы. В свою очередь, для повышения эффективности использования установок генерации электроэнергии на возобновляемых источниках необходимо применять современные преобразователи электроэнергии для достижения максимального КПД. С целью обеспечения непрерывной работы генерирующих установок совместно с централизованной сетью необходимо обеспечить полную и мгновенную синхронизацию. Исследования проводились на основе статистических данных по генерации электроэнергии за счет ветряных турбин, а также метода контурных токов и узловых потенциалов для схем DC-DC и DC-AC-преобразователей. Для подтверждения результатов исследования проведено математическое и компьютерное имитационное моделирование бестрансформаторного DC-DC-преобразователя и разработаны системы управления для обеспечения синхронизации автономной энергосистемы на основе возобновляемых источников энергии с единой энергетической системой. Результаты моделирования показали эффективное применение DC-DC-преобразователей и DC-AC-преобразователей для обеспечения заданного уровня напряжения и синхронизации по фазе ветрогенераторной установки автономной системы электроснабжения с единой энергетической системой.
