本文将聚能装药结构的爆炸聚能原理应用于石材矿山的切割开采之中,首先分析了聚能药包爆炸作用对石材的切割原理,其中,着重研究了炮孔壁上的聚能开裂和裂缝扩展以及贯通的物理过程,推导了裂缝形成过程中各个阶段的力学条件;然后,将聚能切割原理应用于大理石的切割爆破之中,并对现场切割爆破效果和影响聚能效应的因素进行了分析讨论,试验研究表明,文中所得的结论与现场试验的结果相吻合。 In this paper, the principle of explosive energy gathering of charged charge structure is applied to the cutting and mining of stone mines. Firstly, the principle of cutting the stone by the explosion of the energy accumulator is analyzed. In particular, And crack growth and through the physical process, the mechanical condition of each stage in the process of crack formation was deduced. Then, the principle of energy dissipation cutting was applied to the cutting blasting of marble, and the effect of site cutting blasting and the factors affecting the energy gathering effect Analyzed and discussed, experimental studies show that the conclusions obtained in this paper are consistent with the results of the field test.
