摘要:为了研究工业电子雷管在小断面爆破中拒爆的原因，通过水下环境对起爆网络中的电子雷管进行不同强度的冲击波冲击试验。研究发现：电子雷管受冲击作用会出现殉爆、损坏拒爆、暂时失效拒爆、正常发火4种情况；暂时失效是由于芯片模块中电容出现冲击失电，导致剩余电压低于药头发火电压而产生拒爆，但模块内部组件没有被损坏，可以重复起爆；所研究的电子雷管损坏压力为123.66～181.57MPa，暂时失效压力为100.29～123.66MPa，电容开始失电压力为36.35～65.82MPa，抗冲击波强度为100.29MPa。
Abstract:In order to study the reasons for the misfire of industrial electronic detonators in small-section blasting, the electronic detonators in the detonation network were subjected to shock wave impact tests of different intensities through the underwater environment. The study found that the electronic detonators under shock wave impact will have four kinds of situations, including detonation of sympathy, damaged misfire, temporary misfire, and normal fire. Temporary misfire is due to the shock loss of the capacitor in the chip module, which result in the residual voltage lower than the ignition voltage and misfire, but the internal components of the module are not damaged and the explosion can be repeated. The damage pressure of the studied electronic detonator is between 123.66～181.57MPa, the temporary failure pressure is between 100.29～123.66 MPa, the capacitor's initial loss of voltage is between 36.35～65.82MPa, and the shock wave strength is 100.29MPa.
