| 摘 要： | 针对电子雷管应用于小断面爆破中发生拒爆的现象，通过水下环境模拟起爆网络中电子雷管受冲击的情况，对比分析两种典型电子雷管抗冲击性能的差异。结果显示:起爆网络中，当电子雷管受冲击作用时，随着冲击强度的增加，损伤模式依次表现为雷管暂时失效拒爆、电子引火元件结构损坏拒爆和殉爆;且不同工艺技术的产品受损程度差异较大。电子控制模块发生冲击失电，会导致引火药头点火能量不足，从而引起暂时失效拒爆。不同种类电子雷管及电子控制模块产品抗冲击性能差异较大。本试验中，A、B样品最大抗冲击强度分别为100.74 MPa和54.21 MPa；A、B样品的电子控制模块最大抗冲击强度分别为181.36 MPa和54.21 MPa。在生产实践活动中，设计的试验装置及方法适合对电子雷管和电子控制模块产品的抗冲击性能进行检测。

| Abstract: | In view of the phenomenon of misfire of detonation when electronic detonators are used in small section blasting, differences of anti-impact performance between two kinds of typical electronic detonators were compared and analyzed by the simulation of impact of electronic detonator in initiation network in underwater environment. The results show that, when the electronic detonator is impacted, with the increase of the impact intensity, the damage degrees of electronic detonator in the initiation network are represented by temporary failure of detonator, electronic flash components structure damage to misfire and sympathetic detonation, and the damage degree of the products with different technology varies greatly. The temporary failure and misfire is caused by insufficient ignition energy of ignition head caused by impact power loss in electronic control module. Impact resistance of different kinds of electronic detonators and electronic control module products is quite different. The maximum anti-impact strength of Sample A and Sample B is 100.74 MPa and 54.21 MPa, respectively. And the maximum anti-impact strength of the electronic control module of Sample A and Sample B is 181.36 MPa and 54.21 MPa, respectively. The designed experimental device and method are suitable for testing the maximum impact resistance of electronic detonators and electronic control modules in production. |
