We examine the enterprises of the fuel and energy complex of the Tyva Republic in which the in which the coal industry and the heat power industry play a leading role. This complex is a crucial economic sector whereas it has a serious negative impact on the environment. Coal mined on the territory of the republic is currently being used primarily for the production of thermal energy. Tyva experiences a shortage of electricity that is offset by energy from the Unified Power Grid of Siberia. A characteristic of the coal-mining enterprises and heat power generation facilities is provided. For the environmental assessment of the coal-mining enterprises we used the most significant indicators, such as the method of mining and the area of disturbed lands whereas for the heat power generation facilities we took into account the amounts of atmospheric pollutant emissions. Data on pollution of soils and earth materials, groundwater, snow and atmospheric air are given. The most significant environmental problems were revealed for the Kaa-Khem coal mine and in the zone of influence of the Kyzyl thermal power plant located in the urban area of Kyzyl. Some measures for a minimization of environmental stress are considered. The findings are displayed on the environmental map. An original cartographic language was developed for this map compilation, which is represented by the system of graphical point signs for displaying coal deposits, the impact of mining enterprises on the environment, mapping of enterprises in the heat power industry and their environmental indicators. The area map symbols show the density of violations for municipalities. The findings expand the methods of thematic mapping and can be used in governance of environmental management.
