摘要:
电子雷管由于具有安全、可控、可追溯等特点，对民用爆炸物品安全管控及社会安全稳定提供了良好的解决方案。但在井下小孔距爆破中发现，电子雷管拒爆率偏高，严重地影响了爆破安全和电子雷管的推广应用。根据现场模拟试验的结果，分析了小孔距爆破中电子雷管拒爆的原因，发现电子雷管抗冲击振动性能较差，从而出现引火药头被振碎、芯片数据混乱及电容漂移等问题。通过对比不同厂家的电子雷管爆破效果认为，选用高质量、高可靠性的电子雷管，采用合适的起爆方式，可有效地防止电子雷管拒爆。
Abstract:
〗Electronic detonators provide a good solution to the safety control of civil explosives and social security and stability due to their features of safety, controllability and traceability. However, it is found that the misfired rate is high in the underground small holespace blasting. The blasting safety and popularization and application of electronic detonators are seriously affected. This paper is based on the field simulation test results. The main reason of electronic detonator failure in small holespace blasting is the poor antishock vibration performance of electronic detonator. Then there are some problems such as the pulverizing head being broken by vibration, chip data disturbance and capacitor drift. By comparing the blasting effect of electronic detonators from different manufacturers. It is considered that the electronic detonator with high quality and high reliability and the proper initiation mode can effectively prevent the electronic detonator from failing to detonate.
