METHOD OF MISFIRE IDENTIFICATION BY MONITORING VIBRATION OF THE BLASTING WITH DIGITAL ELECTRONIC DETONATOR |
| |
| Abstract: | The causes and hazards of misfire were analyzed in the blasting engineering.Replacing conventional ignition detonator by Lux No.1 digital electronic detonator was put forward.A new method for misfire identification was proposed through combining quantitative calculation characteristic of delay time of digital electronic detonator with waveform analysis of blasting vibration.The results of blasting test and practical engineering application show that the method is more accurate,feasible and easy to be achieved. |
