摘要
削坡减载是露天采场北部边帮综合治理的当务之急，在边坡上进行爆破作业产生震动，对边坡稳定有一定影响。通过对爆破震动测试，得出了边坡体上爆破震动的衰减规律，并对振速、频率、波延时间及加速度进行了分析，提出了较为合理的最大一段装药量及总装药量，为边坡爆破作业提供了一定的科学依据。
Wall cutting and unloading is a task of top priority of comprehensive harness in the north slope of Jinduicheng open pit stope.The vibration by blasting influenced the stability of slope.The attenuation law of blasting vibration on the slope body was reached by test of blasting vibration.The vibration speed,frequency,continuous time and acceleration was analysed,and the total explosive charge volume was raised.It provided a scientific basis for slope blasting.
