摘　　要：在安家岭露天矿北边坡存在大范围滑坡、坍塌的可能性情况下,对该矿生产爆破进行爆破震动测试,通过对测试结果的回归分析得到采场露天爆破地震波的衰减规律,并分析主要参数的合理性。建议通过控制总药量、爆破延时来提高爆破震动的频率,降低由于共振对边坡稳定性造成的影响,为该矿生产爆破设计提供了科学依据。Tending to have the possibility of the large-scale landslide in northern slope at Anjialing Pit,Pingshuo Coal Industry Co, the mining blasting vibration measurement was carried out. The attenuation characteristic of the mining blasting in the slope was obtained and the reasonableness of the main blasting parameters was evaluated. Based on the measurements and resulting analysis suggestions of controlling the total charge quantity with delay blasting to increase vibration frequency were given for reducing the influence on the slope stability caused by resonating.The suggestions also provided a scientific foundation for the mining blasting design.
