Abstract：Based on the orifices interval charge blasting technology, the article carried out the blasting vibration experimental study, and analyzed the vibration effect. The test results show that, compared with the conventional continuous charge, the amplitude of vibration reduction is obvious, the particle vibration velocity is small and the main vibration frequency is high. The interval charge blasting technique is more favorable for the protection of the surrounding buildings.
