Different Types of Explosives Used in Mining

2019-9-4  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.
