FLUID INCLUSION-RELATED MODELING OF COAL PIT HEAPS RECONSTITUTION IN THE EAST DONBASS

The method of fluid inclusion-related modeling of technogenic coal deposits forming is realized through the example of coal pit heaps in the East Donbass. This method is based on the ideas about hydrocarbonic fluidization of pit coals and wall rocks. In this article we use the term “technogenic coal deposits” to mean refuse piles undergoing different stages of thermal reconstitution. Mineralogical-petrographic and fluid inclusion-related factors and criteria are discovered. They determine the propensity of coal pit heaps for auto-thermal destruction. This is of great practical and predicative importance when developing technogenic coal deposits. Standard structure of a burning refuse pile is presented. The following sections can be seen on it: place of spontaneous heating, combustion; zone of oxidizing roasting; zone of reducing roasting; zone oftechnogenic fluidization; zone of relatively fixed rock.

The work is executed at financial support of the Ministry of education and science of the Russian Federation (Project No. 5.1848.2014/K).
