摘要
采用数码雷管起爆技术进行了深孔台阶爆破精确起爆试验,并进行了爆破振动测试。通过对实测爆破振动波形的分析,分析了爆破振动特性,探讨了爆源的空间位置对振动特性的影响,提出了深孔台阶爆破精确起爆的合理段间时差建议值。
The digital detonators detonator technology was taken to precise detonation test in deep-hole bench blasting and monitored blasting vibration. Through analyzed the waveform of the monitored resutls and its characteristic ,the influence of explosive source location to vibration was discussed and then the reasonable time interval of precise detonation in bench blasting was proposed.
