Information agency Credinform represents the ranking of Russian coal mining companies. Coal mining enterprises with the largest volume of annual revenue (TOP-10) were selected for the ranking, according to the data from the Statistical Register for the latest available periods (for 2015 - 2017). Then they were ranked by the revenue volume (Table 1). The analysis was made on the basis of the data of the Information and Analytical system Globas.

Proceeds from the sale of goods, products, works, services – these are monetary amounts or material values in monetary terms, obtained as a result of business activities after the sale of goods and services.
Net profit ratio is a relation of net profit (loss) of a company to sales revenue.

The revenue and ratio show the scale of an enterprise and the effectiveness of its business activities. As a rule, the larger is company's revenue, the higher is its resistance to the effects of negative factors that could be crushing for small and micro enterprises. Revenue also indicates the production capacity of an organization, especially if you look at this indicator in dynamics. By adding to the analysis of the net profit ratio, it is possible to assess realistically the competitiveness of the company in the market. A high value of the net profit ratio (above the industry average) characterizes a more successful position of the enterprise in relation to its competitors.

In 2016, about 30% of coal mining companies had the net profit ratio higher than the industry average one, and in 2017 - only 23.8%. This suggests that, in general, the coal industry is not sufficiently effective in terms of the ability of the majority of companies to compete on an equal footing. To a some extent, this is due to a certain concentration: the TOP-10 companies cover 40% of the entire coal mining industry, and the TOP-25 - already more than 65%.

For getting of the most comprehensive and fair picture of the financial standing of enterprises of this sector it is necessary to pay attention to combination of the two considered indicators and take into account the dynamics of their change. The ranking of TOP-10 companies is presented below (Table 1).
