The authors conducted the analysis of the peculiarities on the destruction of rock formations by means of tunneling and mountain combine tools. They specify key criteria for choosing the rational parameters of cutting executive bodies in mountain combines. The article lists the factors influencing the efficiency of mine rock cutting. It is noted that the key drawback of mountain massif destruction with cutting is that consecutive elementary rock chips separation occurs under the influence of compression loads. The least energy-intensive way of destruction of rocks is a method that involves the destruction of mountain massifs chiefly under the influence of tensile loads, that is, by detachment. A design is proposed which is a combined executive body of the tunneling and cleaning unit including a bar executive and two-sided hydrocylinders-tractors installed inside the bar beam. The operation principle and procedure of the proposed executive body are described. The use of the proposed executive body will allow one to destroy the mountain massif in the most energy-efficient way ensuring high productivity and the lowest specific consumption of cutters.

The oil&gas enterprises have their own safety concerns list. Poor maintenance of equipment is one of the top safety concerns for many enterprises. There are a lot of methods of increasing of safety, but its shouldn’t be used alone. A complex approach and addition the modern technologies in safety ensuring make possible not only increase the quality but increase the efficiently of production. There are a lot of kinds of quality improving of maintenance of electromechanical equipment, one of them are the augmented reality system. This is a new technology and there are no methods and effective estimation for developing and using this technology in industrial production. Developing the special unified modules of augmented reality for maintenance of electromechanical equipment is the actual task. The aim of this research-to identify possible uses, to estimate the effectiveness in ensuring the safety of production and to develop a way of integrating into typical process control systems of the augmented reality system for maintenance of electromechanical equipment.

In this paper, we consider the need to create an algorithmized digital platform for the development of electric charging networks of road transport and to optimize the load on the current power grid complex. In modern conditions, this platform can become an example of a mechanism for public-private partnerships and the development of environmentally friendly transport. The purpose of the platform is to provide users with up-to-date information about the state of the electric vehicle battery, reduce the cost of creating a network charging infrastructure for electric vehicle transport, automated resource accounting for power supply companies, and other services. The use of information technologies to combine the processes of economic relations in the field of energy sales services will attract funds for infrastructure development by increasing the load factor of generating capacities and unloading power centers. In the article, the authors propose a digital platform architecture using modern technologies such as IIoT, Vehicle to Grid (V2G), Machine learning, Big Data.
