What happens if the electronic detonator is checked normal?

The electronic detonator checked normal by the electronic control module is detonated for the second time, the bridge wire fuses normally, which shows that the damage of supply power of the electronic control module is temporary and restorable.

How electronic detonators work in engineering blasting?

The working process of digital electronic detonators during the actual engineering blasting is rough as follows: connect all the electronic detonators to the network and then test the electronic detonators. After the electronic detonator is qualified, Set the delay time of the electronic detonators through the initiation controller.

What is electronic detonator?

Different from the traditional chemical delay detonator, the electronic detonator is controlled by the electronic control module to execute various orders. An electronic control module is vulnerable to impact overload and electronic interference in the explosion process [, , ].

How to make an electronic detonator without the main charge?

The electronic initiating component is put into the aluminum shell with a diameter of 6.9 mm to make an electronic detonator without the main charge and initiating charge head. Fig. 2. Electronic initiating element (including foot wire).

Are electronic detonators safer than non-electric initiation systems?

Although electronic detonators are usually more vulnerable to extraneous electricity than non-electric initiation systems, the paper shows that the net safety benefit in handling and blasting is in favor of electronic detonators, which are the safest initiation system that has ever been offered to the mining industry.

Can electronic detonators be destroyed?

With some electronic detonator systems it is possible to keep a record of destruction of individual detonators due to their unique identity numbers. Electronic detonators that get into the wrong hands (due to theft) cannot be initiated except with their own programming and firing equipment.
