摘要
分析预裂爆破对边坡稳定的影响，提出一种采用预裂减震、超前压缩和孔内阻尼配合的新的预裂爆破法，指出该方法的关键技术措施并计算主要爆破参数。通过在南芬露天铁矿的应用，表明该方法是行之有效的，降震率为６８％，后冲破裂范围减少７８％。
Analyzing the effect of presplitting blasting on slope stability,a new presplitting blasting method combined of presplitting absorbing shock,beforehand compressing with inhole damping is put forward,and the key technical measures and calculation of main parameters are also put forward.According to the test in Nanfan Open Pit,shows the method is available,the absorbing shock rate of this method reachs 68%,the bursting range of back shock reduces 78%.
