な雷管を製造し、提供することを長年の夢としてきた。On the other hand, the composition of explosives of the detonator for detonating explosives is composed of an ignition charge, an explosive charge (primary explosive) and an additive charge (secondary explosive), and the ignition charge causes ignition of the explosive charge, This energy is used to explode the charge. In other words, in the conventional detonator, the existence of the detonator could not be considered without the detonator. However, since the detonator explodes easily with a small amount of energy, safety problems in manufacturing and handling have always been a bottleneck, and many serious accidents have occurred. In addition, at the time of consumption, the detonator and explosive remain for some reason, and it is necessary to safely recover the detonator when removing it. For this reason, detonator manufacturing engineers have long dreamed to manufacture and provide safe detonators that do not use detonators that are highly sensitive to handling.

In the detonator as disclosed in 123299, since a strong restraining force is an absolute condition, the length of the inner tube to be used becomes long and it is necessary to have a sufficient wall thickness, so that it is easy to handle in terms of shape and weight. However, there was a problem in manufacturing cost.

貫通しなければならないことになっている。The above Examples 1 to 4 and Comparative Example 1
The lead plate test performed in 1. used the penetration method. That is, the detonator is erected in the center of the lead plate placed horizontally on the tube to initiate the detonation, and the radial streak and the degree of perforation (diameter of the through hole, etc.) generated on the lead plate.
The strength of the detonator is determined by. Generally, a lead plate with a thickness of 3 to 8 mm is used, but JIS K 48
07 is 40 mm square, 4 mm thick lead plate and diameter 25 m
It is specified to use an iron pipe having a height of m and a height of 30 mm.
Then, a normal detonator is required to penetrate a lead plate having a thickness of 4 mm in the lead plate test.

同じコンパクトな形状を保つことが可能である。INDUSTRIAL APPLICABILITY The present invention uses, as the detonator, an explosive which is a mixture of a secondary explosive used in a conventional charge and an oxidant, instead of the conventional detonator using a highly sensitive explosive. Safe in manufacturing and handling during transportation and consumption. In particular, in the blasting work, even if the detonator remains non-explosive, it is much safer and easier to remove than the conventional product. In addition, it is possible to maintain a compact shape which is almost the same as that of the conventional detonator in structure.
