某露天磷矿山孔口间隔装药振动效应分析

摘要

基于孔口空气间隔装药爆破技术，开展爆破振动试验研究，对其振动效应进行分析。试验结果表明，较常规连续装药具有降振幅度明显，质点振动速度小，主振频率更高的特点。采用该种爆破技术对于周边建（构）筑物的保护更为有利。%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.
