摘要
采用NUBOX-8016型智能振动测试仪过对金宝铁矿开展爆破振动测试,对爆破振动波形进行分析,确定了金宝铁矿爆破峰值振动速度衰减规律,基于经验类比等方法论证了金宝铁矿爆破振动对边坡稳定性的影响。提出金宝铁矿露天爆破振动速度安全允许值,可为金宝铁矿靠帮爆破设计及边坡稳定性维护提供依据。
UBOX-8016 type intelligent vibration measurement instrument is used to carry out blasting vibration test on Jinbao Iron Ore Mine,the blasting vibration waveform is analyzed,and the attenuation law of blasting peak vibration velocity of Jinbao Iron Ore Mine is determined.By empirical analogy and other methods,the influence of blasting vibration of Jinbao Iron Mine on slope stability is demonstrated.The safe allowable value of the vibration velocity of open blasting at Jinbao Iron Mine is proposed,which can provide a basis for the design of side blasting and maintenance of slope stability at Jinbao Iron Mine.
