Technological aspects of ensuring fire and explosion safety in the underground development of pyrite ore deposits

Sulfide ores play an extremely important role in the development of mineral resource base Russia, as a source rare, non-ferrous, and precious metals. However, sulfide ore deposits is associated with risk dust explosions, oxidative processes that lead to spontaneous combustion ores. The article substantiates urgency solving problem reducing risks taking into account changes balance gold-sulfide deposits. To improve safety sulfide-containing deposits, authors developed new methodological approaches assessment explosion hazard dust, based on integration model, laboratory field experiments comprehensive analysis results. methodology for studying main factors integral part industrial system, it provides possibility forecasting, evaluating, promptly determining state potential sources fire pyrite
