Which part of a mine is responsible for the explosive function?

The part of a mine that is responsible for the explosive function is the booster. In explosive ordnance, the booster serves to amplify the energy of the detonator and ensure that the main charge within the mine detonates effectively. The booster typically contains a more powerful explosive than the detonator and is positioned between the detonator and the main explosive charge. Its role is critical, as it helps transfer the energy from the detonator to the main charge, creating a reliable and effective explosive function.

In contrast, the master fuse is essential for igniting the explosive sequence, but it does not directly contain the explosive function. The detonator is designed to initiate an explosion but relies on the booster for the energy necessary to set off the main charge. Lastly, the body of the mine is primarily the casing that holds all the components together and protects them, but it does not contribute to the explosive capability itself. Thus, the booster is the key element that enables the mine to function as intended when triggered.
