Learn About the Different Types of Explosives Used in Mining

Primary vs. Secondary vs. Tertiary Explosives. Primary explosives can be easily detonated due to their extreme sensitivity to heat, friction, impact, static electricity. Mercury fulminate, lead azide or PETN (or penthrite, or more properly Penta Erythritol Tetra Nitrate) are good examples of primary explosives used in the mining industry. They can be found in blasting caps and detonators.
