Land mine

A land mine, or landmine, is an explosive weapon concealed under or camouflaged on the ground, and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although In the case of Spain, the potential of the genus in the phytoremediation of soils has been evaluated through examples of the restoration of coal mining areas in northern Spain [131, 337,338], or(PDF) Biomass production in surface mines: Renewable
