【摘要】 对晋宁磷矿东采区爆破振动对高边坡的影响进行了监测和分析研究。根据爆破振动监测数据,对质点振动速度进行回归分析,得出了爆破振动沿边坡的传播衰减规律。采用ANSYS/LSDYNA数值模拟软件对边坡建模,输入实测爆破振动波形后,研究爆破振动作用下高边坡的动态响应规律。根据数值模拟及实测结果,判断出爆破振动作用下边坡整体不会受破坏,为矿山后续的生产爆破提供了依据。更多还原

【Abstract】 The effects of blasting vibration on high rock slope in east area of Jinning phosphorus open-pit were monitored and analyze.According to the data monitored in blasting vibration,the regression analysis on particle vibration velocity was carried out to obtain the attenuation law of blasting vibration along the slope.The numerical simulation software ANSYS / LS-DYNA was applied on slope modeling,and the laws of dynamic response on high slope were studied after input the measured blasting vibration waveform.According to the numerical simulation and measured results,it was concluded that the slope would not be destroyed under the action of blasting vibration,which provided the basis for the subsequent open-pit blasting.更多还原
