Abstract

Conducting excavations and clearing works on colliery ores in a number of cases is accompanied by sulfide dust explosions, which release a large amount of sulfur dioxide gas, significantly exceeding the allowable by standards, which leads to increased airing time and long downtime of faces, and sometimes to severe poisoning of people. Release of sulfur dioxide gas occurs in conventional faces, not dangerous in terms of sulfide dust explosion, due to its low ignition temperature (about 400-450°С). To improve the safety of blasting operations it is necessary to study the kinetics of ignition and explosion of sulfide dust.
