Abstract
Environmental tension in coal-mining regions of the country is largely determined by the high level of coal production waste. And a significant part of waste is represented by fine fraction 0-3mm of coals, formed in the process of mining, during preparation, transportation, storage, etc. It is difficult to reduce the level of coal losses in the form of slimes and fines by direct combustion due to the complexity of loading and transportation, as well as the combustion process itself. Therefore, this product must be pelletized. The most accessible, studied and technically prepared method of coal fines pelletizing is the briquetting method. Experiments on briquetting of coal fines with the use of clay and starch as binding materials have been carried out.
