Type 72 non-metallic anti-tank mine

Type 72 Non-Metallic is a Chinese circular, plastic bodied landmine which is designed to damage or destroy a vehicle by blast effect.
== Mechanism ==
The mine has a slightly domed pressure plate made from flexible plastic with a raised 6 spoke wagon wheel pattern on top. Type 72 has a telescopic carrying handle molded into the bottom of the mine and a large diameter filler plug on the side just above the handle position. The mine has a crimp around the top edge where the mine body meets the pressure plate. The mine contains 5.4 kg of 50:50 RDX/TNT and is actuated when pressure of 300 kg deforms the flexible plastic pressure plate long enough to release the cocked striker fuze. When the pressure plate is moved approximately 9 mm downwards it exerts pressure on the fuze. If fuzed with the T-72 clear plastic-cased blast resistant fuze, pressure on the top of the fuze will depress the casing which will revolve due to the depression of the spring which is attached to the casing. The revolution is controlled by lugs on the inner fuze assembly which fit in grooves in the fuze casing. When the fuze casing is revolved and depressed sufficiently, the two retaining balls to will fall away in groove in the outer casing, which releases the striker. The striker is driven down by the spring, initiating the detonator, which in turn initiates the booster and the main charge. The mine is blast resistant resistant since rapid depression of the fuze will push the fuze casing straight down without any revolution. The lugs on the inner fuze assembly will then slide into vertical groves instead of the diagonal ones. The striker retaining balls will then be prevented from coming in line with the groves in the outer casing and the striker will not be released. Instead the pressure plate will bounce back into its original position.
