Description
Short description
The electric detonator is composed of a square metal housing and a cover. The electromechanism is mounted in the housing. Buttons for triggering the explosion are on the cover (pressing the button will generate electricity, which runs to the clamps or the conductor). On the side of the housing, two conductors are mounted, on which the conductive mining wire is attached, which connects the lighters with the explosives in the mining field.

Steel, artificial mass, cooper
Dating
1960s

Original use
In the parts of the Idrija ore deposit, where geomechanical solid rocks are located, ore excavation was very difficult. Ore excavation was initially performed manually and with the use of dynamite, which was triggered with the help of the fuse. In the 1960s, in combination with the machines for easier detonation, explosion triggering with delayed electric lighters and electric detonators was introduced. Pressing the button on the cover of the detonator, created electrical energy which ran to the clamps or the conductor. This method of explosion triggering was safer and easier. Nevertheless, this job was only allowed to be performed by qualified miners.
Present use
The electric detonator is preserved, secured and presented as an important mining heritage of Idrija with exceptional universal values. It is a part of the CUDHg mine collection. Visitors can view it within the permanent museum display Anthony's Main Road, namely within the useful warehouse of explosives on the 17th level of the Kropáč mining field. It is a part of the presentation that represents the entire story of mining in the Idrija Mercury Mine and with the related work process.
Original location
The Mining fields of the Idrija Mercury Mine.
Present location
Anthony's Main Road (level I/20 of the Kropáč mining field), Kosovelova 3, SI-5280 Idrija.
