摘要：

The blasting experiment of the cement mortar model reveals that joint inclination affects blasted rock size distribution, which is an important index to evaluate the blasting effect. According to the fractal theory, the relationship is built up between fractal dimension and mass fraction of blasted fragments screened, that is, yx=100 (x/xm)3−D. On the basis of the experiment results, the fractal dimension describing fragment-size distribution is calculated.
