檢查电雷管或电爆線路的导电情况是否良好,对減少拒爆或瞎砲,保証电气爆破作業的安全、可靠,有着重要的作用。 303勘探队創造了一种电雷管导电性檢查器,其構造簡單,只需一个电阻線圈、一个手电池、一个电話受話器(耳机子)即可制做。使用此种檢查器,可以正确地檢查出电雷管的导电情况,从而保証了掘进效率的提高,特别是在目前缺乏正規的檢查仪器的情
Check the electric detonator or electric burst line of the conductive situation is good, to reduce the anti-explosion or blind cannon, to ensure the safety and reliability of electrical blasting, has an important role. The 303 exploration team created an electrical detonator conductivity checker that is simple in construction and requires only one resistance coil, a battery, and a telephone receiver (headphone jack). Using such a checker, the conductivity of the detonator can be correctly checked, thereby ensuring the improvement of driving efficiency, especially in the absence of formal inspection equipment
