摘要(Abstract):
根据分形几何理论,研究了岩石爆破块度的分形特征,发现岩石的爆破块度具有良好的分形结构。探讨了爆破参数与爆破块度分维数之间的关系。笔者认为,对一直困扰我们的由岩石特性引起的爆破成缝的随机性、不规则性和爆破块度分布的复杂性,分形理论可能为岩石爆破后的块度估算、爆前块度的预报和爆破参数的优化研究开创一个新的生长点。
The basic concept of fractional geometry is briefly introduced in this paper, with the fractional trend of fragments and fractional clia-racteristics of rock blasting fragmentation discussed.It is found that there exists very good fractional structure in rock fragments.The fractional method is applied to study the relation between blasting efficiency and blasting frag-mentation, and therefore the rock blasting fragments forecasting and the optimization of blasting parameters can be made. Fractional theory may provide a new powerful approach for forecasting rock blasting fragmentation.
