摘要
分析了地质地形及爆破参数对露天铁矿逐孔爆破震动的影响,根据露天铁矿的地质和地形条件,对原采用爆破技术参数进行了优化,在保证爆破破碎效果的前提下,显著降低了采场边坡和附近民居所在位置的爆破震动效应。
This paper analyzes the impact of geological terrain and blasting parameters of the open-pit iron hole-by-hole blasting vibration, the original blasting parameters were optimized based on geological and topographical conditions of the open-pit iron, under the premise of ensuring blasting crushing effect,significantly reduced pit slope and nearby residential location of blasting vibration effect.
