DEVELOPMENT OF TECHNOLOGICAL RECOMMENDATIONS FOR ENSURING FIRE AND EXPLOSION SAFETY DURING UNDERGROUND DEVELOPMENT OF PYRITE ORE DEPOSITS

Abstract

The urgency of the problem of reducing the risks associated with spontaneous com-bustion of coal ores and sulfide dust explosions has now increased not only in Russia, but al-so abroad, as there have been significant changes in the mineral resource base of the world's leading metal producers. The oxidation of sulfide ores and rocks with air oxygen is an irre-versible and characteristic exothermic reaction that should be taken into account during the extraction and processing of sulfide-containing minerals to prevent spontaneous combustion of ores and explosions of sulfide dust. The article presents the developed technological measures and recommendations aimed at preventing the processes of oxidation and sponta-neous combustion of coal ores and sulfide dust explosions.
