摘要
为研究定向隔振卸压爆破对保留岩体的影响,本文通过利用水泥砂浆模型模拟露天矿山台阶爆破,对不同装药结构的定向卸压隔振爆破与耦合常规装药爆破的累积损伤进行对比。
In order to study the influence of directional pressure-relieved and vibration-insulated blasting on the rock mass,this paper using cement mortar model simulated bench blasting of open-pit mine,the cumulative damage caused by different charging structure of the directional pressure-relieved and vibration-insulated blasting was tested compared with coupling conventional charging blasting.The results show that the cumulative damage to retain rock,using the directional pressure-relieved and vibration-insulated blasting,obviously less than the coupling conventional charging blasting.
