| Abstract: | 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. |
