本文提出了预裂孔爆破减震效碰的数学模型,并导出了相应的计算公式.将计算结果与实测结果进行比较,基本上相符合,从而可用来进行预裂孔爆破设计.
In this paper, the mathematic model of pre-cracking blasting and impacting is put forward, and the corresponding formulas are deduced.The calculated and measured results are basically consistent with each other, which can be used to pre-crack blasting design.
