Dramatic changes in the global energy market due to COVID-19 pandemic, the OPEC+ agreement, and increasing rates of green energy share in the world community have brought negative effects on the oil sector. In the long term, oil will reduce its importance as an energy resource, but for many years, it will continue to play a significant role in the world of energy. The oil industry has huge potential in terms of technical expertise, management, and financial resources to reduce its greenhouse emissions and ensuring an affordable availability of predictable energy. However, nowadays this sector has lost investing attractiveness. It is an interdisciplinary problem with a solution at the intersection of different stakeholders’ interests. The article is a review one and devoted to the issue of the implementation a public-private partnership (PPP) as a key tool that allows the use of the state and the business’ available resources to achieve the sector’s sustainable development and investment attractiveness. Research and analysis of PPP were based on foreign and domestic literature, using classification and generalization methods, retrospective and critical analysis. This paper contains identified groups of drivers, constraints, and recommendations for further successful PPP implementation in the Russian case.

Currently in the Russian Federation there is a large number of methods for determining the economic damage from environmental pollution. They make it possible to assess the quantitative damage caused by the industry to the environment and consider the environmental pollution factor when calculating the economic performance of enterprises. In general, all methods can be reduced to three main types, whose main advantages and disadvantages, as well as applicability for adjusting the performance of enterprises, and inclusion in environmental performance assessment are discussed in this article. The authors proposed a step-by-step procedure for including the factor of negative impact on the environment in the evaluation of companies' performance. First, a preliminary consolidated assessment is made by the method of specific damage. Secondly, the economic effect is calculated by the method of generalized indirect estimates. If necessary, clarification of calculations by the method of direct calculation is carried out. When calculating production efficiency indicators, considering the nature protection activities of the enterprise, a method of accounting for the prevented damage is proposed.

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.
