Again, due to the sheer force of anti-tank mines, few are strong enough to survive repeated blasts. The use of heat is often recommended as a way of detonating a mine or used to simply burn up the components. Various sources of heat have been tried, and more have been suggested but not yet put to the test. In Afghanistan and Cambodia, occassionally fire was used to clear off the dry grass or undergrowth to expose hidden mines which at times would ignite the explosive filling of the mine. Unfortunately, buried mines are often unaffected by the heat, and some other form of clearance has to be done afterwards.
Fire does however clear the undergrowth, which is at times an advantage.
Lasers and microwaves have both been proposed as methods to destroy mines, but so far neither of them has been tested. As with microwave heating, most lasers need a great deal of power and would have to be vehicle mounted.
