Данная работа посвящена исследованию возможности применения слабоспекающихся малометаморфизированых углей в шихте для коксования, что в свою очередь позволит снизить себестоимость угольных шихт без ухудшения качества доменного кокса. Проведенный анализ технологической переработки слабоспекающихся малометаморфизированных углей позволил определить перспективные направления энерготехнологической переработки твердых горючих ископаемых. В работе исследовано влияние глубокого обогащения на свойства слабоспекающихся углей различных шахт. Проведен анализ глубокого обогащения малометаморфизированных углей в тяжелых средах. Изучена природа угольных образцов до и после обогащения.
This paper investigates the possibility of low-metamorphosed caking coal use in the charge for coking, which in its turn will reduce the prime cost of coal charge without quality loss of metallurgical coke. Conducted analysis of technological processing of low-caking low-metamorphosed coal allowed to determine perspective directions of energo-technological processing of solid fossil fuels. The influence of deep beneficiation on the properties of low-caking coal of different mines has been examined. Deep beneficiation of low-metamorphosed coal in dense environment was analyzed. The nature of the coal samples before and after benefication was studied in the paper. The change of technical analysis indicators was marked, namely, the content of ash and total sulfur in coal, their significant reduction after processing, which is a positive factor. The positive influence on the petrographic composition and a sum indicator of components of the different coal samples was revealed. The possibility of low-caking coal use in the energy sector, as well as in coke industry has been determined. Conclusions regarding the reduction of the prime cost of coal charge during coking are drawn.
