雷电对电爆网路早爆的影响

Influence of Thunder and Lightning on Premature Blasting of the Electricity Ignition Circuit

通过分析雷电对电爆网路早爆的诱发成因,探讨在爆破作业中遇到突发雷电时的应对措施,指出:当爆破作业区上空发生直击雷时,不论采用何种起爆网路,都有发生早爆的可能;采用非电起爆系统可以有效地防止非直接雷击引起的早爆;雷雨季节在爆破作业过程中避免将电爆网路组成闭合回路,可以减少爆破作业中因雷电产生的早爆;任何情况下,在爆破作业区上空有雷击发生时,应将所有人员撤离施工现场至安全地区。

The measures how to deal with the thunder and lightning that happen suddenly are discussed by analyzing the cause of premature blasting of the electricity ignition circuit that caused by thunder and lightning. It is pointed out- Premature blasting will probably happen no matter which type of ignition circuit is used ; Using the noelectricity ignition circuit can prevent the premature blasting efficiently ; In thunder storm weather keeping the circuit disconnected will reduce the probability of premature blasting caused by thunder and lightning; When the thunder and lightning happened just over the labor region of blasting, all people should leave the labor region at once and get to a safe region.
