摘要 针对露天矿山的预裂爆破,从力学角度分析了爆破成缝机理,建立了相关的力学模型,介绍了贯通裂缝的形成过程,具有普遍性。并将预裂爆破在金堆城露天矿的应用情况作了介绍。 The mechanism of blasting cracking was analized from the mechanics respect directed at the presplit blasting in open pit. The mechanics models concerned were set up. It has generality for the forming process of connecting cracks. The application conditions in the open pit of JDC were simply recommended.
