摘要
介绍了分形的基本概念和 4种分维数的确定方法 ,探讨了岩石破碎过程中的分形特征 ,推导了岩石爆破块度分布和分形维数的关系式 ,并建立了分维数与爆破参数的关系 ,从而为爆破参数优化进行块度预报提供了科学依据 。
The basic conception of fractal is introduced,and the methods for determining four kinds of values of fractal dimensions are analyzed.Furthermore,the fractal characteristics of rock fracturing are discussed,and the relationship between distribution of rock blasting fragmentation and fractal dimension is educed,and the relationship between fractal dimension and blasting parameters is found.Therefore it provides scientific foundation for the rock blasting framents forecasting and the optimization of blasting parameters.A new method is also provided for investigation of rock fragentatal theory.
