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 article describes the current situation in the global uranium concentrate market, explains the reasons for the formation of an excess amount of finished goods and the subsequent decreasein prices. The authorsevaluated the prospects of using market mechanisms to improve the financial results of Russian uranium mining enterprises. The location of the main mining centers in comparison with the centers of consumption of finished goods, pricing for the products of uranium mining companies, the dynamics of price changes over the past 20 years, the influence of non-market factors on the supply of finished products are analyzed.This study led to the conclusion that the expectation of changes in the market situation is not viable in a long term. The authors outlined the direction to improve the profitability of mining enterprises by introducing technological changes aimed at reducing the cost of the final product.

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.
