Coal dust residual hydrocarbons as a factor of fire and explosion risks increasing in coal mines

Abstract

The residual hydrocarbons of coal dust and coals of Osinnikovskaya mine (Kuzbass) which are allocated from the dust and coal, as well as their fractions by the size, are investigated at thermal influence (under the temperatures of 150-250 °С). The presence of residual hydrocarbons at coal dust and their essential enrichment by the heavy hydrocarbons is established. The coal dust is shown to inherit residual hydrocarbons from the coals which formed it. Presence of the residual hydrocarbons at the coal dust, enriched with heavy hydrocarbons, creates a potential danger of fire and explosions in coal mines.
