• Different Types of Explosives Used in Mining

    Are civil and military explosives the same? In other words, are we using the same explosives in mining and warfare? 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.
