As shown in fig. 1, the wireless electronic detonator with the connecting wire comprises a bottom shell 3, wherein a ground plug 1 is arranged on the lower side of the bottom shell 3, a wireless receiving antenna, a battery and a wireless control module are arranged in the bottom shell 3, the wireless receiving antenna is connected with the wireless control module, and the battery supplies power for the wireless receiving antenna and the wireless control module; the upside of drain pan 3 is connected with connecting wire 5, and the one end of connecting wire 5 is connected with wireless control module, and the other end is connected with wireless initiation electronic detonator 6.

The front end of the ground insert 1 is sharp, and can be inserted into the ground to fix the whole bottom shell 3 on the ground surface. The bottom shell 3 is internally provided with a wireless receiving antenna, a battery, a wireless control module and other parts. The connection line 5 is a three-core connection line for transmitting commands and electrical signals between the control module and the wireless initiation electronic detonator. The length of the connecting line 5 is larger than the depth of the blasthole for placing the detonator. The electronic detonator 6 acts to detonate the explosive in situ.

When in field use, the electronic detonator 6 is placed in the explosive of the blast hole, the electronic detonator 6 is connected with the wireless control module in the bottom shell 3 through the connecting wire 5, the bottom shell 3 is placed outside the blast hole, 400MHz (UHF frequency band) civil communication frequency is used during communication, and the communication mode has the advantages of simple structure, low cost and the like compared with the full wireless detonating electronic detonator (adopting long wave communication) which needs to be placed underground. Because the wireless module in the bottom shell 3 is low in built-in battery small emission power, the distance between an operator and an initiation site is 500-1000 m for safety, and in order to ensure signal transmission, a relay transmitter is arranged at the near end to prolong the wireless control distance, and the communication between the wireless initiation electronic detonator and the operator is ensured through the relay transmitter.
