Abstract

The explosiveness of suspensions of several powders of sulfide ores with a particle size of 1-5 μm in air is experimentally investigated. The air suspension is affected by high-temperature gas detonation products and shock waves with a temperature behind the front exceeding the pyrrhotite ignition temperature. Data on the changes in the content of chemical elements and compounds in ore powders after their exposure to shock waves are obtained by means of X-ray diagnostics. The effect of the air suspension on the parameters of incident and reflected shock waves is determined.
