Sep 04, 2019· Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid-1800s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil engineering application.
Apr 04, 2017· The Office of Mine Safety and Health Research (OMSHR) has conducted research into the factors that increase the production of toxic gases. These factors may be explosives formulation, blasting in wet boreholes, poor confinement, or any other factor that prevents the explosive from detonating properly.
