| Annotation | The elimination of objects that have a negative impact on the environment, occupying an impressive area, is a national-scale task in the field of economics and ecology. The object of the research is ash and slag waste generated during the burning of coal at Chita CHP–2. The subject of research is the study of the possibility of using waste from the fuel complex of the Transbaikal Territory to improve the environmental safety of the territory during their disposal based on the use of the best available technologies. The purpose of the work is to systematize information on the material composition of coal in Transbaikalia and the integrated use of ash and slag waste (ASH) through the use of the best available technologies to minimize emissions into the environment based on the determination of the chemical composition of the ashes of Chita CHP–2. Information analysis (literary and stock sources, normative-technical and scientific-methodological documentation), granulometric and fractional methods were used in the work; atomic emission spectrometry with inductively coupled plasma, semi-quantitative and approximate quantitative spectral analyses. Systematized information on the material composition of Transbaikal coals in order to determine the content of metals in them; conducted analytical studies of the elemental and quantitative composition of the geosystem: «coal – ash - ash slag»; studied the main directions of rational use of the fuel complex of the Transbaikal Territory. It has been established that ash and slag wastes have an increased content of industrially significant elements (La, Y, Li, Ti). It is concluded that the technogenic waste of the Chita fuel complex can be considered as an unconventional mineral source for the extraction of rare and rare earth metals, as well as secondary raw materials in the construction and road industries, in housing and communal services and agriculture |
