爆破振动测试在某铀矿床井下深孔爆破中的应用

Application of blasting vibration measurement to underground deep-hole blasting of a uranium deposit

针对某铀矿床井下原地爆破浸出试验的爆破筑堆施工对地表民居可能产生振动危害,经过2次现场实时爆破振动测试研究,初步总结出该矿床井下大规模爆破的爆破安全距离及毫秒延时最大一段爆破药量的安全判据,对今后的大规模爆破筑堆施工提供设计依据。

Aimed at the potential vibration damage to residents＇ houses on surface after underground deep-hole blasting of a uranium deposit in stope leaching,two real-time blasting vibration measurements were made.The safe distance and safety criterion of maximum charge weight on millisecond delay explosive in large-scale blasting of the uranium deposit were summed up.These data can provide the design basis for future large scale ore stacking by blasting.
