How to achieve safe connection of detonators
2021-09-08With the continuous progress of society and economy, detonators are increasingly widely used in our daily lives. As is well known, although the volume of the detonator is not large, its energy is indeed enormous. If operated carelessly, it can endanger our lives. This article will elaborate on how to connect the detonator to make it safer
Firstly, connect the two ends of the blasting busbar that have been connected in series to the detonator to be discharged to two terminals. At this time, the continuity measurement circuit works and the red indicator light lights up. When the switch is turned to the "charging" position, the transistor begins to oscillate and outputs an alternating voltage through the transformer output terminal. This voltage is rectified by a diode (after 100 rounds are rectified by four times the voltage) to charge the main capacitor; When the charging voltage reaches the rated value, the voltage indicator light will light up, and the stable circuit will enter a stable state, causing the main oscillator circuit to oscillate intermittently. The voltage indicator light will flash, and at this time, the switch will be turned to the "shooting" position to start shooting.
Understanding the safety operation specifications of detonating tubes can make them safer to use
Understanding the safety operation specifications of detonating tubes can make them safer to use and avoid errors during operation. The requirements for receiving, transporting, using, and returning pyrotechnic materials shall still be implemented in accordance with the relevant provisions of the "Blasting Safety Regulations" and the "Management Rules for Civil Explosives" formulated by the company. Each blasting operation surface is connected to the charging line and led out to connect the main blasting tube. Each blasting must establish a list of blasting team leaders and members, clarify the division of responsibilities of the members, and issue blasting orders by the team leader and follow the detonator. The detonation system of the detonator is: detonating tube of each borehole - main detonating tube - detonating needle - copper core wire - detonator. The construction of the courtyard and the introduction of the shallow hole mining room's detonating tube to the turning point of the lower entrance of the courtyard; 10 meters from the secondary blasting detonator; The middle hole engineering excavation detonating tube is led to the lower entrance of the courtyard at the level roadway; 30 meters from the detonating tube in general excavation engineering; The detonating tube of the medium hole large blasting is led to a safe position at the lower end of the courtyard.
