Mineral extraction does not exclude explosions of coal, sulfuric and sulphide dust, the least explosive of these airships is sulphide dust. The ignition and explosiveness of sulphide ores during short-term shock wave heating has not been studied in practice. The purpose of this work is to investigate the explosiveness of air sills of sulfide ores under the impact of shock waves on them. Explosiveness experimental study of sulphide ore powder suspensions with particle sizes of 1-5 μm in the air was carried out. The aerial suspensions were initiated by shock waves with temperature exceeding the ignition temperature of iron sulfides, and also when high-temperature gas detonation products affected them. A structural analysis of the ore powders is performed to establish the particles surface chemical composition change.
