The order of operation of the fire detonator detonation method is:
First, the processing of detonators. Must be individually assembled prior to blasting cap detonators QA, and select a qualified detonator, fuse will have a vertical period, gently insert the detonator, the detonator shell metal should be safe clincher tight mouth opening, cardboard detonator using tape Tighten the mouth or attach a metal hoop tightly so that the fuse is connected to the fire detonator to become the detonator.
Second, the processing of the detonation kit. In the safety zone near the blasting operation surface, the center of the explosive package is tied with a wooden or bamboo awl to a detonator-sized hole. The depth of the hole can be inserted into the detonator. After insertion, the detonator is fixed with a string or tape.
Third, the ignition. The process of detonating a fire detonator is to ignite the fuse, and the flame generated by the fuse causes the detonator to detonate, causing the explosive charge to detonate. Common methods for igniting fuses are:
(1) Match Ignition This method uses a match to ignite a fuse. It is generally used to point a blasthole at a time. If there are too many blastholes, the ignition time is long, which may cause an accident when the personnel cannot be removed.
(2) When the fuse section is used to ignite several fuses, a common fuse with a certain length for ignition is cut obliquely every 2 to 3 cm, the depth of which is half of the diameter of the fuse, and the ignition When the first end of the fuse is ignited, the flame is sprayed out by sequentially folding the slit, and the flame is used to ignite the fuse of each blasthole. The number of slits is equal to the number of blast holes that were originally ignited.
(3) When the ignition tube is used for the ignition method, each fuse is cut to different lengths according to the detonation sequence. The difference between the two is 5cm, the rear end is cut, and a small section of the fuse is added. Fire line, all inserted into the tube to the surface of the medicine cake, tied with hemp rope, only ignite the fire line when ignition. The ignition tube is made of a waxed paper tube, one end is open, one end is closed, and the bottom of the tube is filled with a medicinal cake of 2 to 3 mm thick. In order to prevent the medicinal cake from being burned to deflagration due to the pressure increase, there is a row near the medicine cake. Stomata.
