| 摘 要： | 分析了毫秒延时爆破破岩机理以及毫秒延时爆破的降振机理。针对某铅锌矿存在的爆破振动问题,通过现场试验获取大量监测数据,通过数据分析确定了该矿山生产爆破的最佳间隔时差。研究结果表明,当延时间隔为50ms时,可以使爆破振动错峰叠加,达到平峰降振的作用,同时为该铅锌矿控制爆破振动提供了理论依据及技术支持。

| Abstract: | The rock breaking mechanism and reducing vibration mechanism of millisecond delay blasting are analyzed. To solve the blasting vibration problems in a lead-zinc mine, a large number of monitoring data is obtained through field test and the interval time of the mine blasting is confirmed through data analysis. The results of the study show that when the interval time is 50 ms, it staggers the peak superposition of blasting vibration, which reach a goal of vibration reduction. The results of the study provide a theoretical basis and technical support to control blasting vibration of the lead-zinc mine. |
