RESEARCH OF THE CURRENT STATE AND ASPECTS OF DEVELOPMENT OF PROMISING TECHNOLOGIES FOR PROCESSING COAL WASTE
Abstract
Today, coal is one of the main types of minerals used as a highcalorie fuel for generating electricity and as a raw material for various industries. As global statistics show, some countries have significantly reduced the amount of coal produced due to the transition to green energy. However, on a global scale, the amount of coal mined is gradually increasing from year to year. This trend of increasing production also applies to the Russian Federation. In order to improve the socio-economic indicators of mining regions, the Program for the Development of the Coal Industry of Russia for the period up to 2035 was developed, which assumes an increase in coal production from 485 to 668 million tons. The processes of coal mining and enrichment are associated with the formation of combustible substances (coal chips, coal dust, coal-water suspension) and low-quality coal that require further processing. The study of existing methods for processing these products is an important task that allows us to determine the most appropriate technologies and establish further prospects for improving their efficiency. For this purpose, six of the most common methods of coal waste handling were considered. The advantages, disadvantages, and current problems are determined, and possible areas of their application are outlined. The coal size indicator was used as the main criterion determining the possibility of using a particular method. Research shows that gravity separation and flotation can be most effectively used to prepare coal as a commercial product or pre-process coal waste for other processing technologies. Oil agglomeration and briquetting are good methods for producing low-ash fuel cells and as raw materials for chemical synthesis. Gasification and pyrolysis allow efficient processing of coal waste to produce valuable products and have minimal impact on the environment.
