为研究工业雷管生产线中皮带传输系统的殉爆问题,通过试验确定了100发DDNP起爆药纸壳雷管、100发DDNP起爆药铝壳雷管、100发无起爆药纸壳雷管、100发无起爆药矿用纸壳雷管的殉爆安全距离。根据经验公式估算了100发DDNP起爆药铝壳雷管爆炸的入射超压,并于实际测量的入射超压进行了比较,对两者数据存在差异的原因进行了分析。结果表明,主发雷管爆炸产生的冲击波和热爆炸气体是被发雷管发生殉爆的直接原因。

The safe distance of propagation blast for industrial detonators is tested. The lift-descending method is used in the experiment. The safe distances of propagation blast for 100 DDNP primary explosive carton detonators, 100 DDNP primary explosive aluminum detonators, 100 non-primary explosive carton detonators, and 100 non-primary explosive carton detonators for mining use are obtained. For DDNP primary explosive detonators, the safe distance of propagation blast for aluminum detonator is greater than that for the cardboard detonator. The safe distance of propagation blast for DDNP primary explosive detonator is greater than that for non-primary explosive detonator. The safe distance of propagation blast for non-primary explosive carton detonator for mining use is less than that for non-primary explosive carton detonator. The overpressure measurement in the blast field of detonator is carried out. There is a major difference between calculated results for the pressure field with the experiment results for that. The reason for the difference is analyzed. The ability of detonator initiation is a complex issue. The experimental results indicate that the major factor of detonation for one detonator is the shock wave of the main detonator, however, for the 100 detonators, the shock wave and explosive gases sent by main detonators explosion are the direct cause for propagation blast by rest of detonators.
