The TQ-MI is a relatively simple, pressure-initiated, blast antitank mine. The asphalt impregnated case does provide the mine with a non-metallic construction. However, the addition of metal scrap for additional fragmentation extends the metallic contents to far more than just the fuze components.
No information about functioning.
Nothing else to see.
