The A.P. Mine No. 5 was a British of World War II.[1][2]
Design[]
Parts[]
The mine itself is a cardboard cylinder to avoid detection by metal detectors. [1]The mine trigger is a hollow ebonite rod on top of the mine, which in later versions is replaced with a circular steel pressure plate to increase the trigger
area. [1]Explosive filling is either 50/50 pentolite or RDX/TNT.[1] To save the mine when not in use, a wooden plug is inserted in its fuse well. [1]
Detonation process[]
The mine is activated by downward pressure on the top of the mine, for example by a soldier's foot.[1]This forces down the ebonite rod on top of the mine which goes through the mine collar below it.[1]This releases retaining balls that the collar was holding which in turn release the spring-loaded striker. [1]This then pierces the No. 99 MK I detonator which activates booster charges on either side of it, detonating the mine.[1]
Arming and disarming[]
To arm the mine, first off, if the wooden safety plug is still in the fuse well, remove it.[1]Then insert the No. 99 detonator, and then insert the ebonite rod containing the striker (among other things) in the fuse well above the detonator.[1] Make sure that no pressure is applied to the rod after insertion to avoid accidentally setting off the mine.[1]To disarm the mine do the opposite of arming: remove the striker and then the detonator.
