Background
The electronic detonator is a detonator for controlling the detonation process through the electronic control module, has great advantages in advancement, safety and practicability, and is widely used nationwide at present. The electronic control module installed in the detonator consists of a chip, an electronic element and a connecting circuit, and is a core component of the electronic detonator. The electronic detonator detonation technology has excellent effects in open-air deep hole blasting and demolition blasting, and the safety, reliability, vibration reduction effect and the like are obviously reflected, but the electronic detonator detonation technology has prominent defects in blasting engineering which is limited by space, such as tunnel tunneling blasting, foundation pile blasting, underground mine mining blasting and the like, mainly reflects that the phenomenon of explosion rejection is serious, and has great negative effects on construction safety, beneficial production, cost control and the like. The misfiring phenomenon is mainly caused by the detonator structure, the blasting delay scheme and the blasting environment. The delay and detonation control of the electronic detonator are completed by an electronic control module arranged in the detonator, and the electronic control module does not work once being damaged, so that the detonator is prevented from being detonated. The blasting working face is small, the distance between blast holes is short due to the fact that the blast holes are dense, when the blast holes which are firstly blasted explode in the blasting process, when physical pressure such as shock waves, vibration waves and blasting pile extrusion generated by blasting exceeds the bearing strength of a shell of a rear blasting detonator, the shell of the rear blasting detonator is easily extruded and deformed or even damaged, an electronic control module arranged in the shell of the detonator is simultaneously extruded and damaged and does not work any more, and the electronic detonator fails to work and is rejected. The partial misfiring phenomenon generated by using an electronic detonator detonation technology in blasting engineering such as tunnel tunneling blasting, foundation pile blasting, underground mine mining blasting and the like which are limited by space always becomes a larger risk source in blasting operation and is limited by space, and the misfiring treatment difficulty and the risk degree in the blasting are higher than those of open-air blasting.
