How do mines work?
Landmines activate when the pressure plate on the mine is exposed to enough pressure to trigger it, the firing pin releases and strikes the denotator explosive charge, which causes the explosive charge to explode. Then the detonation of the denotator charge trigger the main explosive charge. When triggered, the main charge’s detonation will convert the stored energy into large volume of hot gas. Those gases will expand and form a ‘blast wind’ which will push towards the surface, causing serious injuries as it has transferred huge amounts of energy into anything blocking its path.
