摘要
为探究爆破作用对边坡变形特征的影响,采用地基合成孔径雷达监测技术,对刚果(金)某露天铜钴矿边坡进行实时在线监测,研究爆破作业条件下整体边坡及局部区域的变形规律。研究结果表明:爆破作业对边坡变形行为的影响呈现明显的空间差异性,其中爆堆邻近区域表现出更显著的变形响应;虽然爆破作用未显著改变边坡整体的最大变形幅度,但引起了平均变形幅度的明显变化。研究结果可为爆破作用下露天矿山边坡稳定性分析及安全监测提供一定参考。
In order to investigate the impact of blasting effects on slope deformation characteristics,this study employed ground-based synthetic aperture radar(GB-SAR)monitoring technology to conduct real-time online monitoring of the slope at an open-pit copper-cobalt mine in the Democratic Republic of the Congo(DRC).The deformation patterns across the entire slope and localized areas under blasting operations were studied.The results indicate that blasting operations exhibit significant spatial heterogeneity in their impact on slope deformation behavior,with areas adjacent to blast piles demonstrating more pronounced deformation responses.Although blasting effect did not substantially alter the maximum deformation amplitude of the overall slope,it induced notable changes in the average deformation amplitude.These findings provide valuable insights for stability analysis and safety monitoring of open-pit mine slopes under blasting effects.
