Environmental safety depends on the level of energy security development. Combustible minerals play a leading role in ensuring energy security. Solid combustible minerals make up a significant proportion in the total mass of combustible minerals. Currently, there is no single universal classification system for solid combustible minerals. Different countries use different systems for classifying coal by grade. At the same time, depending on the classification system, different sets of indicators are taken into account. The main energy accumulator in solid combustible minerals is carbon and a small amount of hydrogen. The energy of solid combustible minerals is directly dependent on the content of these chemical elements. To evaluate and compare different types of solid combustible minerals and their intraspecific differences, based on the presence of the optimal number of indicators of the main energy carriers, which are carbon and hydrogen, the conversion coefficient into conventional anthracite has been developed. The developed conversion coefficient of solid combustible minerals into conventional anthracite makes it possible to analyze the energy value of different types of solid combustible minerals, deposits, layers of solid combustible minerals, different grades of coal, operation of solid combustible mining enterprises, mining and processing enterprises, plants and factories processing solid combustible minerals, the state and prospects for the development of different levels of energy security. In the environmental safety system, the developed coefficient can be used in the development of computer simulation programs in creating protection systems to prevent combustion, fires and explosions in the extraction, use and processing of solid combustible minerals. The proposed option can serve as an additional variety to generalize and improve the existing classification systems, and to motivate to seek new approaches to further classification of solid combustible minerals
