摘　　要：本文聚焦露天铜矿爆破作业,深入探讨爆破参数优化对边坡稳定性的影响。通过理论分析、现场监测数据收集与整理,运用数值模拟手段,详细阐述了不同爆破参数如炮孔间距、排距、装药量等变化时边坡岩体应力、位移及破坏情况的变化。研究结果表明,合理优化爆破参数可有效降低爆破震动对边坡的扰动,减少边坡岩体损伤,提高边坡稳定性,为露天铜矿安全生产及可持续开采提供科学依据。This article focuses on the blasting operation of open-pit copper mines and explores in depth the impact of blasting parameter optimization on slope stability.Through theoretical analysis,on-site monitoring data collection and organization,and numerical simulation methods,the changes in stress,displacement,and failure of slope rock mass under different blasting parameters such as borehole spacing,row spacing,and charge amount were elaborated in detail.The research results indicate that rational optimization of blasting parameters can effectively reduce the disturbance of blasting vibration to slopes,reduce rock damage to slopes,improve slope stability,and provide scientific basis for safe production and sustainable mining of open-pit copper mines.
