The electric fuses were tested using thermal pulse test in different environment temperature using thermal pulse test,and the Rosenthal model was used to calculate the temperature rise of the lectric fuses.

The fuse head is one of the most important parts in the electrical detonator.

In this paper, simulation experiments on HPM effects on igniters are reported, the electric current induced within a mine igniter by HPM is calculated using finite difference-time domain (FD-TD) method.

This article used the silica flour, the porous silica flour and the oxidant tetroxide threelead compounds has prepared a match head, tested its ignition electric current to study theexplosive property on the mixture of the porous silicon and the oxidant tetroxide three leadcompound.
