Energy mechanism of sulphide dust explosion in sublevel mining drawing outlet for high sulphur metal ore mine

摘要

This paper studies the ignition of sulphide dust explosion in the sublevel mining drawing outlet of high-sulphur metal mine on the basis of chemical reaction heat and energy diffusion mechanism. The study shows that the major ignition of the sulphide dust explosion is the combustion of oxidized high sulphure ore, lintel being the major explosion position.
