Abstract

The article presents the results of a study of the combustion processes of technogenically redeposited coal-bearing deposits in the south of the Kuznetsk Basin (Osinnikov coal deposit). Based on lithological and geochemical data of pyrogenically altered coal-bearing deposits of waste heaps, several regularities were revealed. Waste heap burning is a slowly developing progressive process that determines the formation of three zones: red-colored burnt rocks; active combustion (pyrogenesis) and black pyrolysis products. Terricolites are a special newly formed product formed during the pyrogenesis of coal-bearing deposits in the near-surface part of the waste heap, in which the silica content reaches 95%.

Keywords
