Deep hole controlled blasting technology based on precise time delay |
| |
| Abstract: | Discussed the electric detonator initiating technology and its application in deep hole blasting under complex environment combining with engineering practices.Besides,analyzed the hole by hole accurate delay blasting and its vibration effect and control technology in foundation excavation.The results show that the high precision electronic detonators can significantly reduce the strength of blasting vibration,combines with the pre split blasting control,vibration reduction effect is more significant.By optimizing the delay time,a high frequency and low peak waveform may be adjusted,blasting break rock effects and harmful effects can be precise controlled. |
