The TQ-Mi is an obsolete circular Czechoslovakian anti-tank blast mine. The mines body is made of cardboard impregnated with asphalt. A central pressure cap is made of glass, which sits on top of a chemical fuze, which is crushed open onto the booster charge. The booster charge is embedded in the TNT main charge, above which are a number of scrap metal fragments, giving a secondary anti-personnel effect.

It has now been withdrawn from service with the Czech and Slovakian armies.
