Blast resistant mine

A blast resistant mine is a landmine (intended for anti-tank or anti-personnel purposes) with a fuze which is designed to be insensitive to the shock wave from a nearby explosion.

This feature makes it difficult or impossible to clear such mines using explosive minefield breaching techniques.

The sudden impulse from impact or explosion does not have sufficient duration to inflate the bladder and rotate the locking collar, whereas steady pressure from a vehicle's wheel or track does.

A third technique involves the use of a pressure plate with a small surface area yet broad ground coverage like the M1 mine.

Additionally seismic fuzes can be used to detonate mines, based on the characteristic sounds of footsteps or vehicles.
