近年来,微差爆破在矿山大爆破中获得了广泛应用。因此,合理选择起爆电源和设计起爆网络,并在保证可靠的前提下,尽量减少电气准备工作量,是一个值得认真探讨的问题。一、交流与直流电源供电的比较我们用八线示波器对江西803厂生产的工业8号毫秒电雷管进行了电气性能测定,研究了在不同起爆电源(工频交流和直流)、不同的超爆电流(1～3安培)时,成串雷管起爆的拒爆率、延时误差和有效供电
In recent years, the millisecond blasting has been widely used in large blasting of mines. Therefore, a reasonable choice of detonating power and detonating network design, and to ensure reliable under the premise of minimizing the electrical preparation workload is a problem worthy of serious discussion. First, the exchange and DC power supply comparison We use eight-line oscilloscope on the 803 plant in Jiangxi Province industrial No. 8 millisecond electric detonator electrical performance was studied in different detonating power (AC and DC power frequency), different super-blast Current (1-3 amps), the detonation rate of detonators detonated, delay error and effective power supply
