在开拓掘进和小型矿井炮采中,使用大量电雷管。对所使用的电雷管必须事先检测其阻抗或通断,否则往往产生拒爆和瞎炮,不仅影响爆破效果和工程质量,有时还会造成事故。一般小矿缺少专用的雷管阻抗测试仪
In pioneering excavations and mining in small mines, a large number of electric detonators are used. For the electric detonator used, the impedance or on-off of the electric detonator must be detected in advance, otherwise, the detonating and blind guns may often occur, which will not only affect the blasting effect and the quality of the project, but also sometimes cause accidents. General lack of small mine dedicated detonator impedance tester
