摘要
Full-scale and lab-scale blast tests have been done in Swedish Bararp granite to compare the characteristics of particle size distribution curves of full-scale and lab-scale blasting tests. For every full- and lab-scale blast test the total amount of the broken rock was screened from a particle size of 0.075 mm up to plus 500 mm. The particle size distribution curves obtained have been compared with respect to their local slope characteristics. This analysis has shown, that the characteristic of the particle size distribution curves shows a comparable, material specific characteristics for the particle size classes from 0.1 mm up to 10 mm.
