Explosive properties of sulfide dust generated during mining exploration works

Abstract

Mining workings during geological exploration works completely or overwhelmingly pass through the oxidation zone, which is of the greatest interest in the study of dust explosiveness. The variety of factors, on which the oxidation process of sulfide deposits depends, does not make it possible to study the explosivity of dust of sulfide ores in this zone at one of any deposits. Explosive properties of sulfide dust are not fully studied, but it is certain that explosiveness is determined mainly by sulfur, and not only the amount of sulfur in the ore, but also the properties of the minerals in which it is contained ....
